| Title | Tenda W3 V1.0.0.3(2204) Buffer Overflow |
|---|
| Description | A stack-based buffer overflow exists in Tenda w3 V1.0.0.3(2204) in formSetAutoPing at /goform/setAutoPing. The handler processes the ping2 POST parameter and copies it to a stack buffer without proper bounds checking. Supplying a long ping2 string triggers stack corruption, causing a crash and enabling potential control-flow hijacking. The vulnerability is reachable with linkEn=1 and a large ping2 value. |
