A vulnerability, which was classified as critical, has been found 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.
This vulnerability is cataloged as CVE-2026-11450. It is possible to initiate the attack remotely. There is no exploit available.
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.”
