|
## Basic Info
|
|
|
|
The web service is the most **common and extensive service** and a lot of **different types of vulnerabilities** exists.
|
|
|
|
**Default port:** 80 (HTTP), 443(HTTPS)
|
|
|
|
```bash
|
|
PORT STATE SERVICE
|
|
80/tcp open http
|
|
443/tcp open ssl/https
|
|
```
|
|
|
|
```bash
|
|
nc -v domain.com 80 # GET / HTTP/1.0
|
|
openssl s_client -connect domain.com:443 # GET / HTTP/1.0
|
|
```
|
|

## Methodology summary
|
|
|
|
> In this methodology we are going to suppose that you are going to a attack a domain (or subdomain) and only that. So, you should apply this methodology to each discovered domain, subdomain or IP with undetermined web server inside the scope.
|
|
|
|
* [ ] Start by **identifying** the **technologies** used by the web server. Look for **tricks** to keep in mind during the rest of the test if you can successfully identify the tech.
|
|
* [ ] Any **known vulnerability** of the version of the technology?
|
|
* [ ] Using any **well known tech**? Any **useful trick** to extract more information?
|
|
* [ ] Any **specialised scanner** to run (like wpscan)?
|
|
* [ ] Launch **general purposes scanners**. You never know if they are going to find something or if the are going to find some interesting information.
|
|
* [ ] Start with the **initial checks**: **robots**, **sitemap**, **404** error and **SSL/TLS scan** (if HTTPS).
|
|
* [ ] Start **spidering** the web page: It's time to **find** all the possible **files, folders** and **parameters being used.** Also, check for **special findings**.
|
|
* [ ] _Note that anytime a new directory is discovered during brute-forcing or spidering, it should be spidered._
|
|
* [ ] **Directory Brute-Forcing**: Try to brute force all the discovered folders searching for new **files** and **directories**.
|
|
* [ ] _Note that anytime a new directory is discovered during brute-forcing or spidering, it should be Brute-Forced._
|
|
* [ ] **Backups checking**: Test if you can find **backups** of **discovered files** appending common backup extensions.
|
|
* [ ] **Brute-Force parameters**: Try to **find hidden parameters**.
|
|
* [ ] Once you have **identified** all the possible **endpoints** accepting **user input**, check for all kind of **vulnerabilities** related to it.
|
|
* [ ] [Follow this checklist](../../pentesting-web/web-vulnerabilities-methodology.md)
|
|
|
|
## Server Version (Vulnerable?)
|
|
|
|
### Identify
|
|
|
|
Check if there are **known vulnerabilities** for the server **version** that is running.\
|
|
The **HTTP headers and cookies of the response** could be very useful to **identify** the **technologies** and/or **version** being used. **Nmap scan** can identify the server version, but it could also be useful the tools [**whatweb**](https://github.com/urbanadventurer/WhatWeb)**,** [**webtech** ](https://github.com/ShielderSec/webtech)or [**https://builtwith.com/**](https://builtwith.com)**:**
|
|
|
|
```bash
|
|
whatweb -a 1 <URL> #Stealthy
|
|
whatweb -a 3 <URL> #Aggresive
|
|
webtech -u <URL>
|
|
webanalyze -host https://google.com -crawl 2
|
|
```
|
|
|
|
Search **for** [**vulnerabilities of the web application** **version**](../../generic-methodologies-and-resources/search-exploits.md)
|
|
|
|
### **Check if any WAF**

|
_Take into account that the **same domain** can be using **different technologies** in different **ports**, **folders** and **subdomains**._\
|
|
If the web application is using any well known **tech/platform listed before** or **any other**, don't forget to **search on the Internet** new tricks (and let me know!).
|
|
|
|
### Source Code Review
|
|
|
|
If the **source code** of the application is available in **github**, apart of performing by **your own a White box test** of the application there is **some information** that could be **useful** for the current **Black-Box testing**:
|
|
|
|
* Is there a **Change-log or Readme or Version** file or anything with **version info accessible** via web?
|
|
* How and where are saved the **credentials**? Is there any (accessible?) **file** with credentials (usernames or passwords)?
|
|
* Are **passwords** in **plain text**, **encrypted** or which **hashing algorithm** is used?
|
|
* Is it using any **master key** for encrypting something? Which **algorithm** is used?
|
|
* Can you **access any of these files** exploiting some vulnerability?
|
|
* Is there any **interesting information in the github** (solved and not solved) **issues**? Or in **commit history** (maybe some **password introduced inside an old commit**)?

### Automatic scanners
|
|
|
|
#### General purpose automatic scanners
|
|
|
|
```bash
|
|
nikto -h <URL>
|
|
whatweb -a 4 <URL>
|
|
wapiti -u <URL>
|
|
W3af
|
|
zaproxy #You can use an API
|
|
nuclei -ut && nuclei -target <URL>
|
|
|
|
# https://github.com/ignis-sec/puff (client side vulns fuzzer)
|
|
node puff.js -w ./wordlist-examples/xss.txt -u "http://www.xssgame.com/f/m4KKGHi2rVUN/?query=FUZZ"
|
|
```
|
|
|
|
#### CMS scanners
|
|
|
|
If a CMS is used don't forget to **run a scanner**, maybe something juicy is found:
|
|
|
|
[**Clusterd**](https://github.com/hatRiot/clusterd)**:** [**JBoss**](jboss.md)**, ColdFusion, WebLogic,** [**Tomcat**](tomcat/)**, Railo, Axis2, Glassfish**\
|
|
[**CMSScan**](https://github.com/ajinabraham/CMSScan): [**WordPress**](wordpress.md), [**Drupal**](drupal/), **Joomla**, **vBulletin** websites for Security issues. (GUI)\
|
|
[**VulnX**](https://github.com/anouarbensaad/vulnx)**:** [**Joomla**](joomla.md)**,** [**Wordpress**](wordpress.md)**,** [**Drupal**](drupal/)**, PrestaShop, Opencart**\
|
|
**CMSMap**: [**(W)ordpress**](wordpress.md)**,** [**(J)oomla**](joomla.md)**,** [**(D)rupal**](drupal/) **or** [**(M)oodle**](moodle.md)\
|
|
[**droopscan**](https://github.com/droope/droopescan)**:** [**Drupal**](drupal/)**,** [**Joomla**](joomla.md)**,** [**Moodle**](moodle.md)**, Silverstripe,** [**Wordpress**](wordpress.md)
|
|
|
|
```bash
|
|
cmsmap [-f W] -F -d <URL>
|
|
wpscan --force update -e --url <URL>
|
|
joomscan --ec -u <URL>
|
|
joomlavs.rb #https://github.com/rastating/joomlavs
|
|
```
|
|
|
|
> At this point you should already have some information of the web server being used by the client (if any data is given) and some tricks to keep in mind during the test. If you are lucky you have even found a CMS and run some scanner.
|
|
|
|
## Step-by-step Web Application Discovery
|
|
|
|
> From this point we are going to start interacting with the web application.
|
|
|
|
### Initial checks
|
|
|
|
**Default pages with interesting info:**
|
|
|
|
* /robots.txt
|
|
* /sitemap.xml
|
|
* /crossdomain.xml
|
|
* /clientaccesspolicy.xml
|
|
* /.well-known/
|
|
* Check also comments in the main and secondary pages.
|
|
|
|
**Forcing errors**
|
|
|
|
Web servers may **behave unexpectedly** when weird data is sent to them. This may open **vulnerabilities** or **disclosure sensitive information**.
|
|
|
|
* Access **fake pages** like /whatever\_fake.php (.aspx,.html,.etc)
|
|
* **Add "\[]", "]]", and "\[\["** in **cookie values** and **parameter** values to create errors
|
|
* Generate error by giving input as **`/~randomthing/%s`** at the **end** of **URL**
|
|
* Try **different HTTP Verbs** like PATCH, DEBUG or wrong like FAKE
|
|
|
|
#### **Check if you can upload files (**[**PUT verb, WebDav**](put-method-webdav.md)**)**
|
|
|
|
If you find that **WebDav** is **enabled** but you don't have enough permissions for **uploading files** in the root folder try to:
|
|
|
|
* **Brute Force** credentials
|
|
* **Upload files** via WebDav to the **rest** of **found folders** inside the web page. You may have permissions to upload files in other folders.
|
|
|
|
### **SSL/TLS vulnerabilites**
|
|
|
|
* If the application **isn't forcing the user of HTTPS** in any part, then it's **vulnerable to MitM**
|
|
* If the application is **sending sensitive data (passwords) using HTTP**. Then it's a high vulnerability.
|
|
|
|
Use [**testssl.sh**](https://github.com/drwetter/testssl.sh) to checks for **vulnerabilities** (In Bug Bounty programs probably these kind of vulnerabilities won't be accepted) and use [**a2sv** ](https://github.com/hahwul/a2sv)to recheck the vulnerabilities:
|
|
|
|
```bash
|
|
./testssl.sh [--htmlfile] 10.10.10.10:443
|
|
#Use the --htmlfile to save the output inside an htmlfile also
|
|
|
|
# You can also use other tools, by testssl.sh at this momment is the best one (I think)
|
|
sslscan <host:port>
|
|
sslyze --regular <ip:port>
|
|
```
|
|
|
|

|
|
|
|
### Spidering
|
|
|
|
Launch some kind of **spider** inside the web. The goal of the spider is to **find as much paths as possible** from the tested application. Therefore, web crawling and external sources should be used to find as much valid paths as possible.
|
|
|
|

|
|
|
|
### Brute Force directories and files
|
|
|
|
Start **brute-forcing** from the root folder and be sure to brute-force **all** the **directories found** using **this method** and all the directories **discovered** by the **Spidering** (you can do this brute-forcing **recursively** and appending at the beginning of the used wordlist the names of the found directories).\
|
|
Tools:
|
|
|
|
* **Dirb** / **Dirbuster** - Included in Kali, **old** (and **slow**) but functional. Allow auto-signed certificates and recursive search. Too slow compared with th other options.
|
|
* [**Dirsearch**](https://github.com/maurosoria/dirsearch) (python)**: It doesn't allow auto-signed certificates but** allows recursive search.
|
|
* [**Gobuster**](https://github.com/OJ/gobuster) (go): It allows auto-signed certificates, it **doesn't** have **recursive** search.
|
|
* [**Feroxbuster**](https://github.com/epi052/feroxbuster) **- Fast, supports recursive search.**
|
|
* [**wfuzz**](https://github.com/xmendez/wfuzz) `wfuzz -w /usr/share/seclists/Discovery/Web-Content/raft-medium-directories.txt https://domain.com/api/FUZZ`
|
|
* [**ffuf** ](https://github.com/ffuf/ffuf)- Fast: `ffuf -c -w /usr/share/wordlists/dirb/big.txt -u http://10.10.10.10/FUZZ`
|
|
* [**uro**](https://github.com/s0md3v/uro) (python): This isn't a spider but a tool that given the list of found URLs will to delete "duplicated" URLs.
|
|
* [**Scavenger**](https://github.com/0xDexter0us/Scavenger): Burp Extension to create a list of directories from the burp history of different pages
|
|
* [**TrashCompactor**](https://github.com/michael1026/trashcompactor): Remove URLs with duplicated functionalities (based on js imports)
|
|
* [**Chamaleon**](https://github.com/iustin24/chameleon): It uses wapalyzer to detect used technologies and select the wordlists to use.

|
### What to check on each file found
|
|
|
|
* [**Broken link checker**](https://github.com/stevenvachon/broken-link-checker): Find broken links inside HTMLs that may be prone to takeovers
|
|
* **File Backups**: Once you have found all the files, look for backups of all the executable files ("_.php_", "_.aspx_"...). Common variations for naming a backup are: _file.ext\~, #file.ext#, \~file.ext, file.ext.bak, file.ext.tmp, file.ext.old, file.bak, file.tmp and file.old._ You can also use the tool [**bfac**](https://github.com/mazen160/bfac) **or** [**backup-gen**](https://github.com/Nishantbhagat57/backup-gen)**.**
|
|
* **Discover new parameters**: You can use tools like [**Arjun**](https://github.com/s0md3v/Arjun)**,** [**parameth**](https://github.com/maK-/parameth)**,** [**x8**](https://github.com/sh1yo/x8) **and** [**Param Miner**](https://github.com/PortSwigger/param-miner) **to discover hidden parameters. If you can, you could try to search** hidden parameters on each executable web file.
|
|
* _Arjun all default wordlists:_ [https://github.com/s0md3v/Arjun/tree/master/arjun/db](https://github.com/s0md3v/Arjun/tree/master/arjun/db)
|
|
* _Param-miner “params” :_ [https://github.com/PortSwigger/param-miner/blob/master/resources/params](https://github.com/PortSwigger/param-miner/blob/master/resources/params)
|
|
* _Assetnote “parameters\_top\_1m”:_ [https://wordlists.assetnote.io/](https://wordlists.assetnote.io)
|
|
* _nullenc0de “params.txt”:_ [https://gist.github.com/nullenc0de/9cb36260207924f8e1787279a05eb773](https://gist.github.com/nullenc0de/9cb36260207924f8e1787279a05eb773)
|
|
* **Comments:** Check the comments of all the files, you can find **credentials** or **hidden functionality**.
|
|
* If you are playing **CTF**, a "common" trick is to **hide** **information** inside comments at the **right** of the **page** (using **hundreds** of **spaces** so you don't see the data if you open the source code with the browser). Other possibility is to use **several new lines** and **hide information** in a comment at the **bottom** of the web page.
|
|
* **API keys**: If you **find any API key** there is guide that indicates how to use API keys of different platforms: [**keyhacks**](https://github.com/streaak/keyhacks)**,** [**zile**](https://github.com/xyele/zile.git)**,** [**truffleHog**](https://github.com/trufflesecurity/truffleHog)**,** [**SecretFinder**](https://github.com/m4ll0k/SecretFinder)**,** [**RegHex**](https://github.com/l4yton/RegHex\)/)**,** [**DumpsterDive**](https://github.com/securing/DumpsterDiver)**,** [**EarlyBird**](https://github.com/americanexpress/earlybird)
|
|
* Google API keys: If you find any API key looking like **AIza**SyA-qLheq6xjDiEIRisP\_ujUseYLQCHUjik you can use the project [**gmapapiscanner**](https://github.com/ozguralp/gmapsapiscanner) to check which apis the key can access.
|
|
* **S3 Buckets**: While spidering look if any **subdomain** or any **link** is related with some **S3 bucket**. In that case, [**check** the **permissions** of the bucket](buckets/).
|
|
|
|
### Special findings
|
|
|
|
**While** performing the **spidering** and **brute-forcing** you could find **interesting** **things** that you have to **notice**.
|
|
|
|
**Interesting files**
|
|
|
|
* Look for **links** to other files inside the **CSS** files.
|
|
* [If you find a _**.git**_ file some information can be extracted](git.md)
|
|
* If you find a _**.env**_ information such as api keys, dbs passwords and other information can be found.
|
|
* If you find **API endpoints** you [should also test them](web-api-pentesting.md). These aren't files, but will probably "look like" them.
|
|
* **JS files**: In the spidering section several tools that can extract path from JS files were mentioned. Also, It would be interesting to **monitor each JS file found**, as in some ocations, a change may indicate that a potential vulnerability was introduced in the code. You could use for example [**JSMon**](https://github.com/robre/jsmon)**.**
|
|
* You should also check discovered JS files with [**RetireJS**](https://github.com/retirejs/retire.js/) or [**JSHole**](https://github.com/callforpapers-source/jshole) to find if it's vulnerable.
|
|
* **Javascript Deobfuscator and Unpacker:** [https://lelinhtinh.github.io/de4js/](https://lelinhtinh.github.io/de4js/), [https://www.dcode.fr/javascript-unobfuscator](https://www.dcode.fr/javascript-unobfuscator)
|
|
* **Javascript Beautifier:** [http://jsbeautifier.org/](https://beautifier.io), [http://jsnice.org/](http://jsnice.org)
|
|
* **JsFuck deobfuscation** (javascript with chars:"\[]!+" [https://enkhee-osiris.github.io/Decoder-JSFuck/](https://enkhee-osiris.github.io/Decoder-JSFuck/))
|
|
* [**TrainFuck**](https://github.com/taco-c/trainfuck)**:** `+72.+29.+7..+3.-67.-12.+55.+24.+3.-6.-8.-67.-23.`
|
|
* On several occasions, you will need to **understand the regular expressions** used. This will be useful: [https://regex101.com/](https://regex101.com) or [https://pythonium.net/regex](https://pythonium.net/regex)
|
|
* You could also **monitor the files were forms were detected**, as a change in the parameter or the apearance f a new form may indicate a potential new vulnerable functionality.
|
|
|
|
**403 Forbidden/Basic Authentication/401 Unauthorized (bypass)**
|
|
|
|
{% content-ref url="403-and-401-bypasses.md" %}
|
|
[403-and-401-bypasses.md](403-and-401-bypasses.md)
|
|
{% endcontent-ref %}
|
|
|
|
**502 Proxy Error**
|
|
|
|
If any page **responds** with that **code**, it's probably a **bad configured proxy**. **If you send a HTTP request like: `GET https://google.com HTTP/1.1`** (with the host header and other common headers), the **proxy** will try to **access** _**google.com**_ **and you will have found a** SSRF.
|
|
|
|
**NTLM Authentication - Info disclosure**
|
|
|
|
If the running server asking for authentication is **Windows** or you find a login asking for your **credentials** (and asking for **domain** **name**), you can provoke an **information disclosure**.\
|
|
**Send** the **header**: `“Authorization: NTLM TlRMTVNTUAABAAAAB4IIAAAAAAAAAAAAAAAAAAAAAAA=”` and due to how the **NTLM authentication works**, the server will respond with internal info (IIS version, Windows version...) inside the header "WWW-Authenticate".\
|
|
You can **automate** this using the **nmap plugin** "_http-ntlm-info.nse_".
|
|
|
|
**HTTP Redirect (CTF)**
|
|
|
|
It is possible to **put content** inside a **Redirection**. This content **won't be shown to the user** (as the browser will execute the redirection) but something could be **hidden** in there.
|
|
|
|
### Web Vulnerabilities Checking
|
|
|
|
Now that a comprehensive enumeration of the web application has been performed it's time to check for a lot of possible vulnerabilities. You can find the checklist here:
|
|
|
|
{% content-ref url="../../pentesting-web/web-vulnerabilities-methodology.md" %}
|
|
[web-vulnerabilities-methodology.md](../../pentesting-web/web-vulnerabilities-methodology.md)
|
|
{% endcontent-ref %}
|
|
|
