Name of the Vulnerable Software and Affected Versions Advantech WebAccess versions prior to V8.2 20170817

Recommendations For Advantech WebAccess versions prior to V8.2 20170817, update to version V8.2 20170817 or later to resolve the issue. As a temporary workaround, consider restricting the input of user-supplied data to prevent exploitation until a patch is applied.
