Name of the Vulnerable Software and Affected Versions Tenda AC6 version 15.03.06.49 multi TDE01

Description A flaw in the httpd component allows remote attackers to perform OS command injection. The issue exists within the fromSetWirelessRepeat() function located in the '/goform/WifiExtraSet' endpoint, where manipulating the mac or ssid arguments enables the execution of arbitrary operating system commands.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, restrict access to the '/goform/WifiExtraSet' endpoint or avoid using the mac and ssid parameters within that endpoint.
