Authenticated Command Injection on TP-Link TL-WR802N, TL-WR841N and TL-WR840N

A command injection vulnerability was identified in TP-Link TL-WR802N v4, TL-WR841N v14, and TL-WR840N v6 due to improper neutralization of special elements used in an OS command.  In the router configuration import function allows an authenticated attacker to upload a crafted configuration file that results in execution of OS commands with root privileges during port-trigger processing.  
Successful exploitation allows an authenticated attacker to execute system commands with root privileges, leading to full device compromise.

CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
