Introduction
Ivanti Neurons for ITSM, a widely adopted IT service management solution, faces a critical security threat. CVE-2025-22462, an authentication bypass vulnerability, grants unauthenticated attackers full administrative access, placing sensitive organizational data and infrastructure at severe risk. Immediate action and patching are imperative to prevent potential exploitation.
Affected Systems and Versions
The vulnerability specifically impacts the following Ivanti Neurons for ITSM on-premises versions:
- Version 2023.4 and earlier
- Version 2024.2 and earlier
- Version 2024.3 and earlier
Systems exposed directly to the internet without IP restrictions or DMZ configurations are particularly vulnerable.
Technical Information
CVE-2025-22462 results from improper authentication validation within the IIS-hosted web interface of Ivanti Neurons for ITSM. Attackers exploit this flaw by crafting specific HTTP requests that bypass authentication checks entirely, allowing them to gain administrative privileges without credentials.
Attack Vector
- Unauthenticated HTTP requests targeting the IIS web interface.
- Exploitation requires minimal complexity and no prior authentication.
Root Cause
The vulnerability aligns with CWE-288 (Authentication Bypass by Alternate Path), indicating insufficient validation of user sessions or HTTP headers, enabling attackers to circumvent standard authentication mechanisms.
Patch Information
Ivanti has released patches addressing this vulnerability:
- Version 2023.4: Apply May 2025 Security Patch
- Version 2024.2: Apply May 2025 Security Patch
- Version 2024.3: Apply May 2025 Security Patch
Additional Mitigations
- Restrict access to the IIS interface to trusted IP addresses.
- Deploy Ivanti Neurons for ITSM behind a DMZ.
- Monitor and audit administrative login attempts closely.
Detection Methods
Organizations should monitor for the following indicators of compromise (IoCs):
- Unexpected creation of administrative accounts.
- Unauthorized modifications to ITSM workflows or configurations.
- Anomalous network traffic patterns, particularly to unfamiliar IP addresses.
Regular log reviews and anomaly detection systems are recommended to identify potential exploitation attempts.
Vendor Security History
Ivanti has experienced multiple critical vulnerabilities, including:
- CVE-2025-0282: Actively exploited buffer overflow in Ivanti Connect Secure.
- CVE-2025-22457: Remote code execution exploited by China-linked APT groups.
- CVE-2024-7593: Authentication bypass flaw with publicly available exploit code.
These incidents underscore the necessity for Ivanti users to remain vigilant and proactive in applying security updates.
References
Organizations using Ivanti Neurons for ITSM must urgently apply patches and implement recommended security measures to mitigate this critical threat.
