CVE-2025-11622 is a vulnerability classified under CWE-502 (Deserialization of Untrusted Data) affecting Ivanti Endpoint Manager versions 2024 SU3 SR1 and 2022 SU8 SR2. The vulnerability arises because the product improperly handles deserialization of data, allowing a local authenticated attacker to manipulate serialized objects and escalate their privileges within the system. Deserialization vulnerabilities occur when untrusted data is processed without sufficient validation, enabling attackers to execute arbitrary code or alter program logic. In this case, the attacker must have local authenticated access, which means they already have some level of access to the system but can leverage this flaw to gain higher privileges, potentially leading to full administrative control. The CVSS v3.1 score of 7.8 indicates high severity, with attack vector local (AV:L), low attack complexity (AC:L), low privileges required (PR:L), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no exploits are currently known in the wild, the vulnerability poses a significant risk due to the critical nature of endpoint management systems in enterprise environments. Ivanti Endpoint Manager is widely used for managing and securing endpoints, making this vulnerability particularly concerning for organizations relying on it for IT operations and security enforcement.

The impact of CVE-2025-11622 on European organizations can be substantial. Successful exploitation allows attackers with local access to escalate privileges, potentially gaining administrative control over endpoint management infrastructure. This can lead to unauthorized access to sensitive data, disruption of endpoint management services, and the ability to deploy malicious configurations or software across managed devices. Given the central role of endpoint managers in enforcing security policies, a compromise could cascade into broader network compromise, data breaches, and operational downtime. European organizations in sectors such as finance, healthcare, government, and critical infrastructure, which often rely on Ivanti Endpoint Manager for device management and security compliance, face heightened risks. The vulnerability could also undermine regulatory compliance with GDPR and other data protection laws if exploited to access or manipulate personal data.

To mitigate CVE-2025-11622, organizations should: 1) Monitor Ivanti’s official channels for patches and apply them promptly once released, as no patches are currently available. 2) Restrict local access to systems running Ivanti Endpoint Manager to trusted personnel only, minimizing the risk of an attacker gaining the initial foothold. 3) Implement strict access controls and auditing on endpoint management servers to detect and respond to suspicious activities related to deserialization or privilege escalation attempts. 4) Employ application whitelisting and endpoint protection solutions to detect anomalous behavior indicative of exploitation. 5) Conduct regular security assessments and penetration testing focusing on local privilege escalation vectors. 6) Educate administrators about the risks of insecure deserialization and the importance of limiting local authenticated access. 7) Consider network segmentation to isolate endpoint management infrastructure from less secure network zones. These measures collectively reduce the attack surface and improve detection and response capabilities until official patches are deployed.
