Htb Skills Assessment - Web Fuzzing -

This is particularly useful for fuzzing API endpoints that require specific JSON structures or authentication tokens.

Are you stuck on a or flag within the assessment, or did you need a deeper explanation of the ffuf filters ?

With the extensions identified, you can now discover hidden pages and directories. This involves using a recursive scan to thoroughly map out the structure of each vhost. A comprehensive command would be: ffuf -w /path/to/directory-wordlist.txt:FUZZ -u http://vhost.academy.htb:PORT/FUZZ -recursion -recursion-depth 1 -e .ext1,.ext2 -fs DEFAULT_SIZE htb skills assessment - web fuzzing

After finding a valid parameter (e.g., id ), fuzz the value to extract flags or unauthorized data. If the target expects integers, use a custom sequence:

ffuf -w /usr/share/wordlists/dirb/common.txt -u http:// : /FUZZ -e .php,.txt,.bak -recursion -recursion-depth 2 Use code with caution.

Before you can successfully complete the assessment, you must understand several core concepts that underpin all web fuzzing operations. This is particularly useful for fuzzing API endpoints

The default common.txt might not be enough. Try dirbuster or raft wordlists (found in /usr/share/wordlists/ ).

Following these steps systematically will eventually lead you to a page displaying the final flag. You then copy this flag, for example HTBfuzz1n6_7h3_w3b! , and submit it to the portal to complete the module.

: Two different pages might both return 200 OK, but their content sizes will likely differ. Use -fs to filter out the size of the default page or error page. If you share with third parties, their policies apply

The next logical step is to fuzz for subdomains:

Often, the main directory structure yields limited clues. You must check if the server hosts hidden virtual hosts.

: Use tools like ffuf to scan for hidden directories. Common findings often include an /admin/ directory containing sensitive files like index.php or panel.php .
