Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from tp-link. Update tl-wr802n_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
