Title source: cnaExploitation Summary
EIP tracks 1 public exploit for CVE-2026-11450. PoCs published by Hunt-Benito.
AI-analyzed exploit summary This repository contains a functional Python exploit for three unauthenticated command injection vulnerabilities (CVE-2026-11450, CVE-2026-11451, CVE-2026-11452) in GL.iNet GL-MT3000 (Beryl AX) firmware <= 4.4.5. The exploit targets the `/cgi-bin/glc` endpoint and demonstrates command execution via buffer mismatch, quote escape, and password injection techniques.
Description
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."
