AI Analysis
Technical Summary
The GL-iNet GL-MT3000 device (versions 4.4.0 through 4.4.5) contains a command injection vulnerability in the server.set_peer function of the /cgi-bin/glc file in the wg-server.so native plugin. This vulnerability arises from improper handling of the public_key argument, allowing remote attackers to execute arbitrary commands on the device. The vendor has confirmed the vulnerability, and a public exploit exists. No official patch or remediation level has been provided yet.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary commands on affected GL-iNet GL-MT3000 devices without authentication, potentially leading to full system compromise. Given the CVSS 4.0 score of 9.3 (critical), the impact is severe with high exploitability and no required privileges or user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to the affected device's management interfaces to trusted sources only and monitor for exploitation attempts. Follow vendor communications closely for updates on patches or mitigations.
