In every pentest web there is **several hidden and obvious places that might be vulnerable**. This post is meant to be a checklist to confirm that you have searched vulnerabilities in all the possible places.
|
|
|
|
## Proxies
|
|
|
|
{% hint style="info" %}
|
|
Nowadays **web** **applications** usually **uses** some kind of **intermediary** **proxies**, those may be (ab)used to exploit vulnerabilities. These vulnerabilities need a vulnerable proxy to be in place, but they usually also need some extra vulnerability in the backend.
|
|
{% endhint %}
|
|
|
|
* [ ] [**Abusing hop-by-hop headers**](abusing-hop-by-hop-headers.md)
|
|
* [ ] [**Cache Poisoning/Cache Deception**](cache-deception.md)
|
|
* [ ] [**HTTP Request Smuggling**](http-request-smuggling/)
|
|
* [ ] [**H2C Smuggling**](h2c-smuggling.md)
|
|
* [ ] [**Server Side Inclusion/Edge Side Inclusion**](server-side-inclusion-edge-side-inclusion-injection.md)
|
|
* [ ] [**Uncovering Cloudflare**](../network-services-pentesting/pentesting-web/uncovering-cloudflare.md)
|
|
* [ ] [**XSLT Server Side Injection**](xslt-server-side-injection-extensible-stylesheet-languaje-transformations.md)
|
|
|
|
## **User input**
|
|
|
|
{% hint style="info" %}
|
|
Most of the web applications will **allow users to input some data that will be processed later.**\
|
|
Depending on the structure of the data the server is expecting some vulnerabilities may or may not apply.
|
|
{% endhint %}
|
|
|
|
### **Reflected Values**
|
|
|
|
If the introduced data may somehow being reflected in the response, the page might be vulnerable to several issues.
|
|
|
|
* [ ] [**Client Side Template Injection**](client-side-template-injection-csti.md)
|
|
* [ ] [**Command Injection**](command-injection.md)
|
|
* [ ] [**CRLF**](crlf-0d-0a.md)
|
|
* [ ] [**Dangling Markup**](dangling-markup-html-scriptless-injection.md)
|
|
* [ ] [**File Inclusion/Path Traversal**](file-inclusion/)
|
|
* [ ] [**Open Redirect**](open-redirect.md)
|
|
* [ ] [**Prototype Pollution to XSS**](deserialization/nodejs-proto-prototype-pollution/#client-side-prototype-pollution-to-xss)
|
|
* [ ] [**Server Side Inclusion/Edge Side Inclusion**](server-side-inclusion-edge-side-inclusion-injection.md)
|
|
* [ ] [**Server Side Request Forgery**](ssrf-server-side-request-forgery/)
|
|
* [ ] [**Server Side Template Injection**](ssti-server-side-template-injection/)
|
|
* [ ] [**Reverse Tab Nabbing**](reverse-tab-nabbing.md)
|
|
* [ ] [**XSLT Server Side Injection**](xslt-server-side-injection-extensible-stylesheet-languaje-transformations.md)
|
|
* [ ] [**XSS**](xss-cross-site-scripting/)
|
|
* [ ] [**XSSI**](xssi-cross-site-script-inclusion.md)
|
|
* [ ] [**XS-Search**](xs-search.md)
|
|
|
|
Some of the mentioned vulnerabilities requires special conditions, others just require the content to be reflected. You can find some interesting polygloths to test quickly the vulnerabilities in:
|
|
|
|
{% content-ref url="pocs-and-polygloths-cheatsheet/" %}
|
|
[pocs-and-polygloths-cheatsheet](pocs-and-polygloths-cheatsheet/)
|
|
{% endcontent-ref %}
|
|
|
|
### **Search functionalities**
|
|
|
|
If the functionality may be used to search some kind of data inside the backend, maybe you can (ab)use it to search arbitrary data.
|
|
|
|
* [ ] [**File Inclusion/Path Traversal**](file-inclusion/)
|
|
* [ ] [**NoSQL Injection**](nosql-injection.md)
|
|
* [ ] [**LDAP Injection**](ldap-injection.md)
|
|
* [ ] [**ReDoS**](regular-expression-denial-of-service-redos.md)
|
|
* [ ] [**SQL Injection**](sql-injection/)
|
|
* [ ] [**XPATH Injection**](xpath-injection.md)
|
|
|
|
### **Forms, WebSockets and PostMsgs**
|
|
|
|
When websocket, post message or a form allows user to perform actions vulnerabilities may arise.
|
|
|
|
* [ ] [**Cross Site Request Forgery**](csrf-cross-site-request-forgery.md)
|
|
* [ ] [**Cross-site WebSocket hijacking (CSWSH)**](cross-site-websocket-hijacking-cswsh.md)
|
|
* [ ] [**PostMessage Vulnerabilities**](postmessage-vulnerabilities.md)
|
|
|
|
### **HTTP Headers**
|
|
|
|
Depending on the HTTP headers given by the web server some vulnerabilities might be present.
|
|
|
|
* [ ] [**Clickjacking**](clickjacking.md)
|
|
* [ ] [**Content Security Policy bypass**](content-security-policy-csp-bypass/)
|
|
* [ ] [**Cookies Hacking**](hacking-with-cookies/)
|
|
* [ ] [**CORS - Misconfigurations & Bypass**](cors-bypass.md)
|
|
|
|
### **Bypasses**
|
|
|
|
There are several specific functionalities were some workarounds might be useful to bypass them
|
|
|
|
* [ ] [**2FA/OTP Bypass**](2fa-bypass.md)
|
|
* [ ] [**Bypass Payment Process**](bypass-payment-process.md)
|
|
* [ ] [**Captcha Bypass**](captcha-bypass.md)

|
|
* [ ] [**Reset Forgotten Password Bypass**](reset-password.md)
|
|
* [ ] [**Registration Vulnerabilities**](registration-vulnerabilities.md)
|
|
|
|
### **Structured objects / Specific functionalities**
|
|
|
|
Some functionalities will require the **data to be structured on a very specific format** (like a language serialized object or a XML). Therefore, it's more easy to identify is the application might be vulnerable as it needs to be processing that kind of data.\
|
|
Some **specific functionalities** my be also vulnerable if a **specific format of the input is used** (like Email Header Injections).
|
|
|
|
* [ ] [**Deserialization**](deserialization/)
|
|
* [ ] [**Email Header Injection**](email-header-injection.md)
|
|
* [ ] [**JWT Vulnerabilities**](hacking-jwt-json-web-tokens.md)
|
|
* [ ] [**XML External Entity**](xxe-xee-xml-external-entity.md)
|
|
|
|
### Files
|
|
|
|
Functionalities that allow to upload files might be vulnerable to several issues.\
|
|
Functionalities that generates files including user input might execute unexpected code.\
|
|
Users that open files uploaded by users or automatically generated including user input might be compromised.
|
|
|
|
* [ ] [**File Upload**](file-upload/)
|
|
* [ ] [**Formula Injection**](formula-injection.md)
|
|
* [ ] [**PDF Injection**](xss-cross-site-scripting/pdf-injection.md)
|
|
* [ ] [**Server Side XSS**](xss-cross-site-scripting/server-side-xss-dynamic-pdf.md)
|
|
|
|
### **External Identity Management**
|
|
|
|
* [ ] [**OAUTH to Account takeover**](oauth-to-account-takeover.md)
|
|
* [ ] [**SAML Attacks**](saml-attacks/)
|
|
|
|
### **Other Helpful Vulnerabilities**
|
|
|
|
This vulnerabilities might help to exploit other vulnerabilities.
|
|
|
|
* [ ] [**Domain/Subdomain takeover**](domain-subdomain-takeover.md)
|
|
* [ ] [**IDOR**](idor.md)
|
|
* [ ] [**Parameter Pollution**](parameter-pollution.md)
|
