## Technical details

An OS Command Injection vulnerability (CWE-78) exists in Pandora FMS within the WebServerModuleDebug component. The flaw stems from improper neutralization of special elements used in an OS command, allowing an attacker to inject and execute arbitrary system commands. The attack vector is network-based and requires low-privileged (PR:L) authentication. Successful exploitation grants the attacker the ability to execute code with the privileges of the web server user, potentially leading to full system compromise. The vulnerability is present in versions 777 through 800; version 800.1 is reported as a potential fix version in CPE configurations.
