TOTOLINK AC1200 Wireless Router A3002RU V2.1.1-B20230720.1011 is vulnerable to Buffer Overflow. The formWlEncrypt CGI handler in the boa program fails to limit the length of the wlan_ssid field from user input. This allows attackers to craft malicious HTTP requests by supplying an excessively long value for the wlan_ssid field, leading to a stack overflow. This can be further exploited to execute arbitrary commands or launch denial-of-service attacks.

TOTOLINK AC1200 Wireless Router A3002R Firmware V1.1.1-B20200824 is vulnerable to Buffer Overflow. In the boa server program's CGI handling function formWlEncrypt, there is a lack of length restriction on the wlan_ssid field. This oversight leads to potential buffer overflow under specific circumstances. For instance, by invoking the formWlanRedirect function with specific parameters to alter wlan_idx's value and subsequently invoking the formWlEncrypt function, an attacker can trigger buffer overflow, enabling arbitrary command execution or denial of service attacks.
