Ivanti Endpoint Manager Mobile API Authentication Bypass
CVE-2025-4427 is an authentication bypass vulnerability in the API component of Ivanti Endpoint Manager Mobile (EPMM) 12.5.0.0 and earlier. The flaw allows an unauthenticated attacker to access protected API resources without supplying valid credentials. The provided content further characterizes the issue as affecting protected EPMM API endpoints and attributes it to an insecure Spring Framework implementation. In observed attack chains, CVE-2025-4427 was used as the pre-authentication access primitive to reach functionality that should have required authentication, and it was subsequently chained with CVE-2025-4428 to achieve unauthenticated remote code execution on exposed EPMM systems.
