Name of the Vulnerable Software and Affected Versions: Tenda W20E version 15.11.0.6

Description: A critical issue affects the formSetRemoteWebManage function of the file /goform/SetRemoteWebManage, leading to a stack-based buffer overflow when the remoteIP argument is manipulated. This can be exploited remotely, potentially impacting the confidentiality, integrity, and availability of protected information by sending specially crafted POST requests.

Recommendations: For Tenda W20E version 15.11.0.6, as a temporary workaround, consider disabling the formSetRemoteWebManage function until a patch is available. Restrict access to the /goform/SetRemoteWebManage endpoint to minimize the risk of exploitation. Avoid using the remoteIP 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.
