Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

An issue was discovered in Open-AudIT 3.3.1. There is shell metacharacter injection via attributes to an open-audit/configuration/ URI. An attacker can exploit this by adding an excluded IP address to the global discovery settings (internally called exclude_ip). This exclude_ip value is passed to the exec function in the discoveries_helper.php file (inside the all_ip_list function) without being filtered, which means that the attacker can provide a payload instead of a valid IP address.
