Ivanti warns of critical Neurons for ITSM auth bypass flaw
Ivanti has released security updates for its Neurons for ITSM IT service management solution that mitigate a critical authentication bypass vulnerability. Tracked as CVE-2025-22462, the security flaw can let unauthenticated attackers gain administrative access to unpatched systems in low-complexity attacks, depending on system configuration. As the company highlighted in a security advisory released today, organizations that followed its guidance are less exposed to attacks. "Customers who have followed Ivanti's guidance on securing the IIS website and restricted access to a limited number of IP addresses and domain names have a reduced risk to their environment," Ivanti said. "Customers who have users log into the solution from outside their company network also have a reduced risk to their environment if they ensure that the solution is configured with a DMZ." Ivanti added that CVE-2025-22462 only impacts on-premises instances running versions 2023.4, 2024.2, 2024.3, and earlier, and said that it found no evidence that the vulnerability is being exploited to target customers. Product Name Affected Version(s) Resolved Version(s) Ivanti Neurons for ITSM (on-prem only) 2023.4, 2024.2, and 2024.3 2023.4 May 2025 Security Patch 2024.2 May 2025 Security Patch 2024.3 May 2025 Security Patch The company also urged customers today to patch a default credentials security flaw (CVE-2025-22460) in its Cloud Services Appliance (CSA) that can let local authenticated attackers escalate privileges on vulnerable systems. While this vulnerability isn't exploited in the wild either, Ivanti warned that the patch won't be applied correctly after installing today's security updates and asked admins to reinstall from scratch or use these mitigation steps to ensure their network is protected from potential attacks.
