Name of the Vulnerable Software and Affected Versions Tenda FH1203 version 2.0.1.6

Description The issue is related to a stack overflow in the formSetClientState function, which can be exploited to execute arbitrary code. This is due to a buffer overflow in memory, allowing a remote attacker to potentially gain control. The deviceId parameter in the formSetClientState function is specifically vulnerable to this overflow.

Recommendations For Tenda FH1203 version 2.0.1.6, consider disabling the formSetClientState function until a patch is available to prevent exploitation via the deviceId parameter. Restrict access to this function to minimize the risk of remote code execution. Avoid using the deviceId parameter in the affected function until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
