Technical details

An OS Command Injection vulnerability exists in the terminal action handler of Pheditor due to improper sanitization of the 'dir' POST parameter. While the 'command' parameter is checked for shell metacharacters, the 'dir' parameter is passed directly into a shell_exec() call (e.g., 'cd ' . $dir . ' && ...'). An attacker with valid credentials and terminal permissions can inject shell metacharacters (like semicolons) into the 'dir' parameter to bypass the TERMINAL_COMMANDS whitelist and achieve Remote Code Execution (RCE). This allows for full system compromise under the context of the web server user (e.g., www-data). The issue is resolved in version 2.0.4 by implementing proper shell argument escaping.
