| Title | Tenda HG10 HG7_HG9_HG10re_300001138 Denial of Service |
|---|
| Description | A buffer overflow vulnerability exists in the Tenda HG10 AC1200 Dualband Wi-Fi xPON ONT router. The vulnerability is located in the Boa web server's formDOMAINBLK interface and is related to the handling of the blkDomain parameter. Because the user-controllable parameter is copied without sufficient length validation, a remote attacker can submit an overlong value through a crafted HTTP request. Successful exploitation may cause a denial-of-service condition and could potentially lead to arbitrary code execution depending on memory layout and runtime protections. |
