What is CVE-2024-34198?

The TOTOLINK AC1200 Wireless Router A3002RU V2.1.1-B20230720.1011 contains a buffer overflow vulnerability in its WlEncrypt CGI handler. This flaw occurs due to insufficient validation of input length for the wlan_ssid field, allowing malicious users to send crafted HTTP requests with excessively long values. Such actions can cause a stack overflow, which may enable attackers to execute arbitrary commands on the device or conduct denial-of-service attacks, compromising network integrity and availability.
