description

Ivanti Cloud Services Application version 5.0.8 is affected by an authentication bypass. A remote attacker able to reach the service can add or remove trusted EPM Core certificate entries without authenticating.

mitigation

Restrict network access to the application to trusted administrative systems and review certificate-entry changes for unauthorized modifications. Apply vendor-provided remediation when it becomes available.
