Summary

When DLP is active, the UserCheck Web Portal has an input-handling issue in the UserChoice flow. An attacker with access to the UserCheck Ask page could manipulate stored DLP/UserCheck incident information, leading to loss of incident entries, incorrect handling of pending approvals, or resource impact if abused repeatedly.

Risk Assessment

Risks include disruption of DLP functionality, loss of incident data, and potential resource exhaustion. Exposure is reduced if the UserCheck Portal is not accessible from untrusted networks.

Recommendation

Restrict access to the UserCheck Portal to trusted networks only. Apply vendor patches if available. Monitor the system for abuse.
