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

Description A critical issue affects the R7WebsSecurityHandler function of the /goform/execCommand file, leading to a stack-based buffer overflow when the password argument is manipulated. This can be exploited remotely, allowing an attacker to execute arbitrary code using a specially crafted POST request.

Recommendations As a temporary workaround, consider disabling the R7WebsSecurityHandler function until a patch is available. Restrict access to the /goform/execCommand file to minimize the risk of exploitation. Avoid using the password 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.
