Title
Authenticated Command Injection on TP-Link TL-WR802N, TL-WR841N and TL-WR840N
Summary
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.
Severity ?
