CVE-2026-34797

8.7 highEPSS 1.3%

High (8.7) in endian firewall community. EPSS 1.3% chance of exploitation in the next 30 days.

Endian Firewall version 3.3.25 and prior allow authenticated users to execute arbitrary OS commands via the DATE parameter to /cgi-bin/logs_smtp.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.
