CH22 V1.0.0.1
Vulnerability details
The Tenda CH22 V1.0.0.1 firmware has a buffer overflow vulnerability in the fromqossetting function. The v8 variable receives the page parameter from a POST request and is later passed to the sprintf function. However, since the user can control the input of page , the statement sprintf(s, "qos_list.asp?page=%s", v8); can cause a buffer overflow.
