HighCVSS 7.3Summary
A vulnerability was detected in GL.iNet GL-MT3000 version 4.4.5, affecting the dlopen function in the /usr/lib/oui-httpd/rpc library. Manipulating the dev_name argument results in command injection, allowing for remote attacks.
Risk Assessment
The organization is exposed to remote attacks that could lead to unauthorized command execution on the device. Exploiting this vulnerability may have serious security implications for the system.
Recommendation
It is advisable to upgrade to version 4.7 or later to mitigate the risks associated with this vulnerability. The changes in method-level validation at the HTTP /rpc layer block the possibility of exploiting this flaw.
Original NVD description (English source)
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."
