Name of the Vulnerable Software and Affected Versions Advantech WebAccess version 8.4.5

Description The issue is related to insufficient authentication data validation in the software.

Recommendations For Advantech WebAccess version 8.4.5, consider restricting access to loading .zip files until a patch is available. As a temporary workaround, limit the privileges of authenticated users to minimize the risk of exploitation.
