Technical details

An OS command injection vulnerability (CWE-78) exists in Endian Firewall version 3.3.25 and earlier within the /cgi-bin/logs_smtp.cgi script. 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 into the parameter to execute arbitrary commands with the privileges of the web server. This attack is reachable over the network but requires valid user credentials.

Affected products

Endian Firewall <= 3.3.25
