Totolink EX1200L router is vulnerable to Buffer Overflow in the login functionality in cgi-bin/cstecgi.cgi endpoint. This vulnerability could be exploited to cause the program to crash and to execute code remotely. This allows the attacker to perform actions as root including reading and editing data, as well as bricking the router. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 9.3.5u.6146_B20201023 but may also affect other versions.
