CVE-2026-18601

Name of the Vulnerable Software and Affected Versions GL.iNet GL-MT3000 versions prior to 4.4.6

Description Command injection is possible via remote exploitation in the ovpn-client.so Native Plugin. The issue exists within the ovpn-client.check config() function located in the /cgi-bin/glc file, where manipulating the filename argument allows for the execution of arbitrary commands.

Recommendations Update GL.iNet GL-MT3000 to version 4.4.6 or later. As a temporary mitigation, restrict access to the /cgi-bin/glc endpoint or avoid using the filename argument within the ovpn-client.check config() function.
