Name of the Vulnerable Software and Affected Versions Advantech WebAccess versions prior to 7.2

Description The issue is related to a stack-based buffer overflow that allows remote attackers to execute arbitrary code. This is achieved by providing a long NodeName parameter.

Recommendations For versions prior to 7.2, update to version 7.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the webvact.ocx module to minimize the risk of exploitation. Avoid using long values for the NodeName parameter in the affected API endpoint until the issue is resolved.
