A vulnerability was detected in Totolink A7000R 4.1cu.4154. This affects the function setUnloadUserData of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument plugin_name results in command injection. It is possible to launch the attack remotely. The exploit is now public and may be used.
Weakness
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
