Name of the Vulnerable Software and Affected Versions Tenda AC500 version 2.0.1.9(1307)

Description A critical issue affects the formSetCfm function of the file /goform/setcfm, leading to a stack-based buffer overflow when the funcpara1 argument is manipulated. This can be exploited remotely, potentially allowing an attacker to execute arbitrary code using a specially crafted POST request.

Recommendations For Tenda AC500 version 2.0.1.9(1307), as a temporary workaround, consider disabling the formSetCfm function until a patch is available. Restrict access to the /goform/setcfm endpoint to minimize the risk of exploitation. Avoid using the funcpara1 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.
