Name of the Vulnerable Software and Affected Versions Tenda TX9 version 22.03.02.10

Description A critical issue is related to the function sub 42CB94() in the /goform/SetVirtualServerCfg file, which is associated with a stack-based buffer overflow when handling the list parameter. This can be exploited remotely by sending a specially crafted POST request, potentially impacting the confidentiality, integrity, and availability of protected information.

Recommendations For Tenda TX9 version 22.03.02.10, as a temporary workaround, consider disabling the sub 42CB94() function until a patch is available. Restrict access to the /goform/SetVirtualServerCfg endpoint to minimize the risk of exploitation. Avoid using the list parameter 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.
