Name of the Vulnerable Software and Affected Versions: Harris Ormed Self Service versions prior to 2019.1.4

Description: The issue allows an authenticated user to view W-2 forms belonging to other users via an arbitrary empNo value to the "ORMEDMIS/Data/PY/T4W2Service.svc/RetrieveW2EntriesForEmployee" URI, thus exposing sensitive information including employee tax information, social security numbers, home addresses, and more.

Recommendations: For versions prior to 2019.1.4, update to version 2019.1.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the "ORMEDMIS/Data/PY/T4W2Service.svc/RetrieveW2EntriesForEmployee" URI to minimize the risk of exploitation. Avoid using arbitrary empNo values in the affected URI until the issue is resolved.
