CVE-2026-34791: 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 logs_proxy. cgi component. Authenticated users can exploit improper input validation of the DATE parameter to execute arbitrary operating system commands. This occurs because the parameter is used to build a file path passed to a Perl open() call without sufficient sanitization. The vulnerability has a high severity with a CVSS 4. 0 score of 8. 7. No patch or official fix information is currently provided.
AI Analysis
Technical Summary
CVE-2026-34791 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 to /cgi-bin/logs_proxy.cgi. This parameter is used to construct a file path that is passed to a Perl open() call. Due to incomplete regular expression validation, an authenticated user can inject arbitrary OS commands, potentially leading to command execution with the privileges of the affected process.
Potential Impact
Successful exploitation allows an authenticated user to execute arbitrary OS commands on the Endian Firewall system. This can lead to unauthorized system control, data compromise, or disruption of firewall operations. The vulnerability is rated high severity with a CVSS score of 8.7, indicating significant risk if exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the affected endpoint to trusted users only and monitor for suspicious activity. Avoid exposing the vulnerable interface to untrusted networks. Follow vendor communications closely for updates on patches or mitigations.
