CVE-2026-11450: Command Injection in GL.iNet GL-MT3000
A vulnerability was detected in GL.iNet GL-MT3000 4.4.5. This affects the function dlopen in the library /usr/lib/oui-httpd/rpc/ of the component Path Normalization Handler. Performing a manipulation of the argument dev_name results in command injection. It is possible to initiate the attack remotely. Upgrading to version 4.7 mitigates this issue. It is advisable to upgrade the affected component. The vendor confirms: " From version 4.7 onward, we have enabled method‑level validation at the HTTP /rpc layer. nas‑web.eject_disk is no longer in the whitelist of allowed methods. Consequently, directly calling eject_disk through the default /rpc endpoint returns Invalid params, preventing entry into subsequent dangerous functions and blocking the remote exploit chain described in the report."
AI Analysis
Technical Summary
This vulnerability in GL.iNet GL-MT3000 4.4.5 involves command injection via the dlopen function in the Path Normalization Handler component. Remote attackers can exploit improper validation of the dev_name argument to execute arbitrary commands. The vendor mitigated the issue in version 4.7 by implementing method-level validation on the HTTP /rpc endpoint and disallowing the nas-web.eject_disk method, which prevents the remote exploit chain.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary commands on the affected device, potentially compromising system integrity and confidentiality. The CVSS 4.0 base score is 6.9 (medium severity), indicating a significant but not critical risk. There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade the GL.iNet GL-MT3000 device to version 4.7 or later, where method-level validation at the HTTP /rpc layer is enabled and the vulnerable nas-web.eject_disk method is removed from the allowed methods. This official fix prevents the remote exploit chain. No additional mitigation steps are indicated by the vendor.
