| Title | UTT (AiTai) HiPER 810G <= v3v1.7.7-171114 Buffer Overflow |
|---|
| Description | A critical buffer overflow vulnerability exists in the UTT HiPER 810G router. The vulnerability can be triggered through the /goform/formFireWall management interface. Due to missing boundary checks, user-controlled input is copied into a fixed-size memory buffer using the unsafe function:
strcpy((char *)(InstPointByIndex + 228), src_1);
Because strcpy does not validate input length, attackers can supply an overly long parameter value, resulting in memory corruption and denial of service. |
