| tiêu đề | GL.iNet GL-MT3000 4.4.5 Command Injection |
|---|
| Mô tả | An unauthenticated command injection vulnerability exists in the `/cgi-bin/glc` endpoint of the affected product. The `nas-web.so` plugin forwards the `set_proto_config` JSON request via libcurl HTTP POST to the local `gl_nas_sys` root daemon. The `gl_nas_sys` FTP protocol handler (`FUN_0045dc80`) extracts the `media_dir` parameter from the JSON payload and passes it unsanitized into two `snprintf()` + `system()` calls that construct shell commands wrapped in single quotes. An attacker can include a single quote (`'`) in `media_dir` to break out of the quoting context, inject shell metacharacters (`;`, `>`, `#`), and execute arbitrary commands as root. |
