A vulnerability was found in TOTOLINK A3600R 4.1.2cu.5182_B20201102. It has been classified as critical. Affected is the function setLanguageCfg of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument langType leads to buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. VDB-272598 is the identifier assigned to this vulnerability. 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.
