Technical details

An OS command injection vulnerability exists in Endian Firewall version 3.3.25 and prior within the /cgi-bin/logs_firewall.cgi component. The vulnerability is rooted in the improper validation of the 'DATE' parameter, which is used to construct a file path passed directly to a Perl open() call. Due to incomplete regular expression validation, an authenticated attacker can inject shell metacharacters to execute arbitrary commands with the privileges of the web server. This is a network-reachable exploit requiring low-level authentication (PR:L).
