CVE-2026-34795: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') (CWE-78) in Endian Endian Firewall
Endian Firewall version 3.3.25 and earlier contains an OS command injection vulnerability in the DATE parameter of /cgi-bin/logs_log.cgi. Authenticated users can exploit this flaw because the DATE parameter is used unsafely in a Perl open() call due to incomplete input validation. This allows arbitrary OS command execution with the privileges of the affected process. The vulnerability has a high severity score of 8.7. No patch or official fix information is currently provided, and no known exploits are reported in the wild.
AI Analysis
Technical Summary
CVE-2026-34795 is an OS command injection vulnerability (CWE-78) affecting Endian Firewall version 3.3.25 and prior. The issue arises from improper neutralization of special elements in the DATE parameter passed to /cgi-bin/logs_log.cgi. This parameter is used to construct a file path that is passed to a Perl open() call without sufficient validation, enabling authenticated users to inject arbitrary OS commands. The vulnerability has a CVSS 4.0 base score of 8.7, indicating high severity with network attack vector, low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an authenticated user to execute arbitrary OS commands on the Endian Firewall system, potentially leading to full system compromise depending on the privileges of the affected process. This can impact system confidentiality, integrity, and availability. There are no known public exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict authenticated user access to trusted personnel only and monitor for suspicious activity related to the /cgi-bin/logs_log.cgi endpoint. Avoid exposing the management interface to untrusted networks.
