CVE-2025-22462 is a critical authentication bypass vulnerability (CWE-288) affecting Ivanti Neurons for ITSM (on-premises deployments) in versions prior to 2023.4, 2024.2, and 2024.3 with the May 2025 Security Patch. This vulnerability allows a remote attacker with no authentication or user interaction to gain administrative access to the affected system. The flaw lies in the authentication mechanism, which can be bypassed remotely, enabling full control over the IT Service Management platform. Given the administrative privileges obtained, an attacker can manipulate IT workflows, access sensitive organizational data, modify configurations, and potentially disrupt IT operations. The vulnerability has a CVSS v3.1 base score of 9.8, indicating critical severity with high impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the ease of exploitation and the critical nature of the flaw make it a significant risk. Ivanti Neurons for ITSM is widely used by enterprises for managing IT services, assets, and workflows, making this vulnerability particularly dangerous in environments relying on on-premises deployments. The lack of required privileges or user interaction lowers the barrier for exploitation, increasing the urgency for patching and mitigation.

For European organizations, this vulnerability poses a severe risk to IT service management infrastructure. Compromise of Ivanti Neurons for ITSM can lead to unauthorized administrative access, enabling attackers to alter IT service workflows, access confidential data, and disrupt critical IT operations. This can result in operational downtime, data breaches involving personal and corporate information, and compliance violations under regulations such as GDPR. Given the central role of ITSM platforms in managing organizational IT assets and services, exploitation could cascade into broader network compromise or service outages. European organizations with on-premises Ivanti Neurons deployments are particularly vulnerable, as cloud versions are not affected. The potential impact extends to sectors with high reliance on ITSM systems, including finance, healthcare, manufacturing, and government agencies, where disruption or data loss can have significant economic and reputational consequences.

Organizations should immediately verify their Ivanti Neurons for ITSM version and apply the May 2025 Security Patch or upgrade to versions 2023.4, 2024.2, or 2024.3 as applicable. Until patched, restrict network access to the Ivanti Neurons for ITSM management interfaces by implementing network segmentation and firewall rules to limit exposure to trusted IP addresses only. Employ strict monitoring and logging of all access attempts to the ITSM platform to detect any anomalous or unauthorized activities. Conduct regular audits of administrative accounts and permissions within the platform to identify potential misuse. Additionally, implement multi-factor authentication (MFA) at the network or VPN level to add an extra layer of protection, as the vulnerability bypasses application-level authentication. Organizations should also prepare incident response plans specific to ITSM compromise scenarios and ensure backups of critical ITSM configurations and data are maintained securely to enable rapid recovery.
