Name of the Vulnerable Software and Affected Versions Advantech WebAccess versions prior to 8.1

Description The issue allows remote attackers to cause a denial of service due to out-of-bounds memory access. Additionally, there is a remote code execution vulnerability via an uncontrolled format string in the BwOpcSvc.dll sprintf function.

Recommendations For versions prior to 8.1, update to version 8.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the webvrpcs Service to minimize the risk of exploitation. Avoid using the sprintf function in the BwOpcSvc.dll until the issue is resolved.
