Name of the Vulnerable Software and Affected Versions Tenda W15E version 15.11.0.14

Description A critical issue was found in the function formAddDnsForward of the file /goform/AddDnsForward. The manipulation of the argument DnsForwardRule leads to a stack-based buffer overflow. This can be exploited remotely, potentially affecting the confidentiality, integrity, and availability of protected information by sending a specially crafted request.

Recommendations For Tenda W15E version 15.11.0.14, as a temporary workaround, consider disabling the formAddDnsForward function until a patch is available. Restrict access to the /goform/AddDnsForward endpoint to minimize the risk of exploitation. Avoid using the parameter DnsForwardRule in the affected endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this issue.
