Nisha McDonne completes a Try Hack Me walkthrough on the Ignite challenge, aiming to exploit a remote code execution vulnerability in Fuel CMS 1.4.1.
The first steps are to identify open ports and services, and then enumerate the target to find useful information.
Fuel CMS version 1.4.1 is identified as the vulnerable component, for which multiple remote code execution vulnerabilities are discovered.
The exploit is imported and executed, allowing command execution on the target as the www-data user.
This user’s permissions are then escalated to those of the root user, allowing the user to retrieve flags and gain complete access to the system.
To mitigate such vulnerabilities, it is essential to implement patching, configuration hardening, and good coding practices, such as robust input validation.
