Authentication Bypass in Ivanti Neurons for ITSM

IdentifiersCVE-2025-22462CWE-288· Authentication Bypass Using an…

CVE-2025-22462 is an authentication bypass vulnerability in Ivanti Neurons for ITSM on-premises deployments affecting versions before 2023.4, 2024.2, and 2024.3 unless the May 2025 Security Patch has been applied. The issue is described as improper authentication validation in the IIS-hosted web interface, allowing a remote attacker to send crafted HTTP requests that bypass normal authentication checks. The available context indicates the flaw may involve insufficient validation of user sessions or HTTP headers, enabling access to privileged functionality without prior authentication.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a remote unauthenticated attacker to gain full administrative access to the affected Ivanti Neurons for ITSM instance. This can enable complete compromise of the application environment, including unauthorized creation of administrative accounts, modification of ITSM workflows and configurations, and access to sensitive operational data and administrative functions.

Mitigation

If you can’t patch tonight, do this now.

Until patching is completed, restrict access to the IIS-hosted web interface to trusted IP addresses only, avoid direct internet exposure, and place the application behind a DMZ or equivalent network segmentation controls. Closely monitor and audit administrative login activity, review logs for anomalous requests and suspicious authentication behavior, and investigate indicators such as unexpected creation of administrative accounts, unauthorized workflow or configuration changes, and anomalous outbound or inbound network traffic to unfamiliar IP addresses.

Remediation

Patch, then assume compromise.

Apply Ivanti's May 2025 Security Patch for the affected Ivanti Neurons for ITSM on-premises release train. Specifically, organizations should update affected deployments in the 2023.4, 2024.2, and 2024.3 versions to the vendor-provided patched builds. Because the flaw permits unauthenticated administrative compromise, patching should be treated as urgent, especially for internet-exposed IIS deployments.
