| タイトル | GL.iNet GL-MT3000 4.4.5 Command Injection |
|---|
| 説明 | An authenticated command injection vulnerability exists in the `iwinfo.scan` ubus RPC method of the affected product. The `iwinfo.so` plugin exposed by rpcd accepts a `device` parameter that undergoes only blobmsg type validation (BLOBMSG_TYPE_STRING). The raw parameter is passed through `iwinfo_backend()` into `libiwinfo.so`, where the MTK backend probe uses `strstr()` substring matching to select the backend, but the device remapping logic inside the MTK scan function uses `strcmp()` exact matching. An attacker can craft a device string that passes the substring probe but fails the exact remap, causing the raw payload to flow directly into `sprintf(buf, "iwpriv %s set SiteSurvey=", device)` followed by `system(buf)`, resulting in root command execution. |
