AI Analysis
Technical Summary
This vulnerability affects the Tenda AC6 router firmware 15.03.06.49_multi_TDE01. It is an OS command injection flaw in the fromSetWirelessRepeat function of the /goform/WifiExtraSet endpoint in the httpd component. By manipulating the mac or ssid arguments, an attacker with high privileges can remotely execute arbitrary operating system commands. The vulnerability is remotely exploitable without user interaction and has a CVSS 4.0 score of 5.1. Public exploit code is available. No official patch or vendor advisory has been published to date.
Potential Impact
Successful exploitation allows an attacker with high privileges to execute arbitrary OS commands remotely on the affected device. This could lead to unauthorized control or disruption of the router's operation. However, the impact is limited by the requirement for high privileges and the low to limited impact on confidentiality, integrity, and availability as per the CVSS vector.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the device's management interface to trusted networks and users only. Monitor for unusual activity related to the /goform/WifiExtraSet endpoint. Avoid exposing the router's management interface to untrusted networks.
