A vulnerability, which was classified as critical, was found in TOTOLINK EX1200L 9.3.5u.6146_B20201023. Affected is the function setDefResponse of the file /www/cgi-bin/cstecgi.cgi. The manipulation of the argument IpAddress leads to stack-based buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
The product writes data past the end, or before the beginning, of the intended buffer.
