AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Endian Firewall versions 3.3.25 and prior

Description Authenticated users can execute arbitrary OS commands through the DATE parameter in the '/cgi-bin/logs firewall.cgi' endpoint. This is due to an incomplete regular expression validation when constructing a file path using the DATE parameter value, which is then passed to a Perl open() call, leading to command injection.

Recommendations Update Endian Firewall to a version later than 3.3.25.
