CVE-2020-14077

Name of the Vulnerable Software and Affected Versions TRENDnet TEW-827DRU versions through 2.06B04

Description The issue is a stack-based buffer overflow in the ssi binary, allowing an authenticated user to execute arbitrary code. This can be achieved by sending a POST request to the "apply.cgi" endpoint with a sufficiently long wps sta enrollee pin key, specifically through the actions set sta enrollee pin wifi1 or set sta enrollee pin wifi0.

Recommendations For TRENDnet TEW-827DRU versions through 2.06B04, as a temporary workaround, consider restricting access to the "apply.cgi" endpoint to minimize the risk of exploitation. Avoid using the wps sta enrollee pin key 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 vulnerability.
