The vulnerability is located at the web endpoint /goform/ConfigWirelessBase_5g, triggered by the POST parameter ssid.
Unsafe function strcpy((char *)(v8 + 40), src_1); is used without bounds checking. Supplying an overlong SSID payload leads to memory corruption and remote denial of service, crashing the target router.
The vendor UTT has been notified via official email [email protected], complete sent mail record is available.

Valid POST POC is ready to reproduce the crash. |
