Description
Endian Firewall version 3.3.25 and prior allow authenticated users to execute arbitrary OS commands via the DATE parameter to /cgi-bin/logs_proxy.cgi. The DATE parameter value is used to construct a file path that is passed to a Perl open() call, which allows command injection due to an incomplete regular expression validation.
Analysis
Remote command execution in Endian Firewall Community ≤3.3.25 allows authenticated users to inject OS commands through the DATE parameter in /cgi-bin/logs_proxy.cgi due to incomplete input validation in Perl open() calls. Attack requires only low-privilege authentication (CVSS PR:L) with network access and no user interaction. …

Remediation
Within 24 hours: Identify and inventory all Endian Firewall Community instances running version 3.3.25 or earlier in your environment using network scanning and asset management tools. Within 7 days: Implement network segmentation to restrict access to the affected /cgi-bin/logs_proxy.cgi endpoint using host-based or perimeter firewalls; disable remote management access where feasible; audit and revoke unnecessary low-privilege user accounts with firewall access. …
