Several community members have published their solutions to the Web Fuzzing Skills Assessment. These can serve as excellent references if you get stuck:
-H : Adds or modifies HTTP headers (crucial for VHost fuzzing). -X : Specifies the HTTP method (GET, POST, etc.). -d : Sends POST data.
In an HTB assessment, you are expected to document:
Finds : id=1 returns admin info.
Brute-forcing, by contrast, is a more targeted approach that focuses on systematically trying many possibilities for a specific value, such as a password or an ID number. In the context of the skills assessment, you will primarily be doing a form of targeted brute-forcing—guessing directory names, file names, parameter names, and subdomains—rather than raw fuzzing with malformed data. However, the distinction is subtle, and the module treats them as overlapping techniques.
The assessment may hide a second application on a different Virtual Host .
While multiple tools exist, the Skills Assessment primarily focuses on:
Before typing ffuf or gobuster , you must understand why HTB places such heavy emphasis on fuzzing. htb skills assessment - web fuzzing
If you find a parameter like debug or file , you can then fuzz its value . For example, ?file=FUZZ to look for Local File Inclusion (LFI).
ffuf -u http://10.10.10.200/api/v1/status?user_id=FUZZ -w numbers.txt -mr 'admin'
This discovery phase typically reveals a subdomain such as hidden .
Streaming/ticketing sites rely heavily on APIs which are often under-documented and vulnerable to parameter fuzzing. Key Tools for Web Fuzzing ffuf -u http://10
Testing identified parameters with different payloads (such as IDs or usernames) to look for unauthorized data access. 3. Subdomain and VHost Fuzzing
The real world is too large to scan manually. Search engines, APIs, and internal apps rely on obscurity. Fuzzing removes that obscurity.
