If you'd like to dive deeper into any of these steps, I can provide: The used for initial discovery. A Python script to automate the Gitea hook exploit. The Fail2Ban configuration details for the root exploit.
Once you have a shell, you will likely find yourself inside a . Escaping the Container hackfail.htb
Add a command to one of the scripts (like iptables-multiport.conf ) that creates a SUID binary or sends a reverse shell. If you'd like to dive deeper into any
Older versions of Gitea are susceptible to various vulnerabilities, including through Git hooks. If you can gain administrative access to a repository, you can often execute commands on the underlying server. The Attack Path Once you have a shell, you will likely
Ensure that configuration files for security tools like Fail2Ban are only writable by the root user.
Gitea is the primary vector for gaining a foothold on this machine. Identifying the Vulnerability
Navigating to the IP address on port 80 reveals a custom web application. Further directory busting or clicking through links often reveals a development sub-domain or a linked service. In the case of HackFail, you will encounter a instance, a self-hosted Git service popular among developers. 🏗️ Phase 2: Initial Access (Exploiting Gitea)
