DescriptionCVE.org

A vulnerability was determined in GL-iNet GL-MT3000 up to 4.4.5. The affected element is the function wg-server.generate_publickey of the file /cgi-bin/glc of the component wg-server.so Native Plugin. Executing a manipulation of the argument private_key can lead to command injection. The attack may be launched remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure and confirmed the existence of the vulnerability.

AnalysisAI

Remote command injection in the GL-iNet GL-MT3000 travel router (firmware 4.4.0-4.4.5) allows unauthenticated network-adjacent or internet-exposed attackers to execute arbitrary OS commands by supplying a maliciously crafted private_key argument to the WireGuard server public key generation endpoint at /cgi-bin/glc. The vendor has confirmed the vulnerability, and a public proof-of-concept exploit is available on GitHub, significantly lowering the barrier to exploitation. …

Vulnerability AssessmentAI

Exploitation The `/cgi-bin/glc` endpoint hosting the `wg-server.generate_publickey` function must be reachable from the attacker's network position. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) represents the most severe possible attack profile: unauthenticated, remotely exploitable, no special attack requirements, and no user interaction needed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with network access to the GL-MT3000's management interface sends a crafted HTTP POST request to `/cgi-bin/glc` targeting the WireGuard server key generation function, embedding shell metacharacters such as a semicolon or backtick within the `private_key` parameter value. The `wg-server.generate_publickey` function passes the unsanitized argument to an OS shell command, causing the injected payload - for example a reverse shell or credential extraction command - to execute with the privileges of the web server process, which on embedded GL-iNet devices is typically root. …
Remediation No vendor-released patched firmware version has been identified in the available data - patch availability is unconfirmed at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.
