CVE-2024-4242

Name of the Vulnerable Software and Affected Versions: Tenda W9 version 1.0.0.7(4456)

Description: The issue is related to a stack-based buffer overflow in the formwrlSSIDget function of the /goform/wifiSSIDget file. This can be exploited by manipulating the ssidIndex argument, allowing a remote attacker to execute arbitrary code by sending specially crafted POST requests. The attack may be initiated remotely.

Recommendations: For Tenda W9 version 1.0.0.7(4456), as a temporary workaround, consider disabling the formwrlSSIDget function until a patch is available. Restrict access to the /goform/wifiSSIDget file to minimize the risk of exploitation. Avoid using the ssidIndex argument in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
