Summary

Control Web Panel (CWP) before 1.29 contains an OS command injection flaw in the loopback API /valid_token/ route. The unvalidated 'user' parameter is passed unescaped into a shell_exec() call, which lets a crafted request run shell metacharacters as commands (CWE-78). An unauthenticated attacker with network access to the loopback API can execute arbitrary commands as root. The CVSS 4.0 vector indicates a local attack vector with low privileges required.

Description from the CNA

Control Web Panel (CWP) before webpanel_version 1.29 contains an OS command injection vulnerability in the loopback API /valid_token/ route that allows unauthenticated attackers to execute arbitrary commands as root by injecting shell metacharacters into the unvalidated 'user' parameter. Attackers can send a crafted request to the /valid_token/ route, which passes the parameter unescaped into a shell_exec() call.
