DescriptionIn the WA300 V5.2cu.7112_B20190227 firmware has a buffer overflow vulnerability in the loginauth function. The v12 variable receives the http_host parameter from a POST request. However, since the user can control the input of http_host, the statement strcpy(v28, v12); can cause a buffer overflow injection vulnerability.
