Navigating to http://hackfail.htb uncovers a custom application portal. Thorough manual inspection and automated fuzzing are necessary to find the flaw. 1. Source Code and Logic Analysis
Below is the technical information and a suggested structure for your report based on common penetration testing methodologies.
The real flag is hidden in a SQLite DB inside the Tomcat temp directory, requiring sudo -l to exploit a custom binary /usr/bin/failcheck — a SUID binary vulnerable to command injection via --log parameter.
Testing for SSTI involves injecting mathematical expressions like 7*7 . If the application returns 49 , you have a confirmed path to RCE. 4. Privilege Escalation: Climbing the Ladder hackfail.htb
To prepare a penetration testing report (or "paper") for the machine on Hack The Box, you should structure your document according to standard industry reporting formats.
Possible database ports (e.g., 3306) or internal services (e.g., 8080, 8000) exposed mistakenly. Exploitation Approach:
The script works by checking:
: Identifying standard web flaws like Local File Inclusion (LFI) or misconfigured administrative interfaces. 3. Privilege Escalation
If the application logs user-agent strings or other headers and you can find a way to include that log file via a Local File Inclusion (LFI), you can achieve Remote Code Execution (RCE).
Falafel.htb is a masterfully designed difficulty machine that tests multiple skills: web application enumeration, SQL injection, hash manipulation, file upload exploitation, and creative privilege escalation through group abuse. Navigating to http://hackfail

Search for internal configuration files containing database passwords or API keys. Look for cron jobs running scripts with loose permissions.
