Tenda PW201A v1.0.5 has a buffer overflow in SafeMacFilter's page parameter, allowing DoS via crafted HTTP requests.
Vulnerability
A buffer overflow vulnerability exists in the SafeMacFilter function of Shenzhen Tenda Technology Co., Ltd Tenda PW201A v1.0.5, specifically within the TENDA_HTTPD binary. The vulnerability is triggered by the page parameter, which is processed by the websGetVar function and subsequently used in an sprintf command, leading to a buffer overflow. The vulnerable code path is reachable via HTTP requests [1].
Exploitation
An attacker can exploit this vulnerability by sending a crafted HTTP request to the SafeMacFilter CGI endpoint. This request should include a page parameter with a value significantly longer than expected, such as a string of 888 or more characters. This crafted request can trigger the buffer overflow [1].
Impact
Successful exploitation of this vulnerability can lead to a Denial of Service (DoS) condition. This may manifest as a process crash or device instability, rendering the device inoperable for legitimate users [1].
Mitigation
