What it detects

This rule flags HTTP webserver requests using the POST method where the URI query contains /SAAS/jersey/manager/api/migrate/tenant. Attackers may use this kind of request path as part of an attempted remote code execution against VMware Workspace ONE Access. Detection relies on webserver telemetry capturing HTTP method and the requested URI query string.
