| Title | totolink A3002MU Hh-B20211125.1046 Buffer Overflow |
|---|
| Description | A buffer overflow vulnerability exists in the TOTOlink A3002MU router. The vulnerability is located in the /bin/boa web server's formPortFw interface and is related to the handling of the service_type parameter. Because the firmware does not properly validate the length of this user-controllable input, a remote attacker can send a crafted HTTP request containing an overlong value. Successful exploitation may cause a denial-of-service condition and could potentially lead to arbitrary code execution. |
