Harris · Harris Ormed Self Service · CVE-2019-18626
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.
