A vulnerability, which was classified as critical, was found in TOTOLINK A3600R 4.1.2cu.5182_B20201102. This affects the function setdeviceName of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument deviceMac/deviceName leads to buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-272595. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
