CVE-2025-5450 is a medium-severity vulnerability identified in Ivanti Connect Secure and Ivanti Policy Secure products, specifically affecting versions prior to 22.7R2.8 and 22.7R1.5 respectively. The root cause is improper access control in the certificate management component, where client-side enforcement of server-side security policies is insufficient. This vulnerability falls under CWE-602, which relates to client-side enforcement of server-side security, meaning that security controls intended to be enforced on the server are instead partially or wholly enforced on the client side, allowing bypass by an attacker. In this case, a remote authenticated administrator with read-only privileges can exploit this flaw to modify settings that should be restricted, effectively escalating their privileges beyond their intended scope. The vulnerability requires the attacker to have authenticated admin access but only with read-only rights, and no user interaction is needed beyond authentication. The CVSS v3.1 score is 6.3, indicating a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), and impacts on confidentiality, integrity, and availability all rated low (C:L/I:L/A:L). There are no known exploits in the wild at the time of publication, and no patch links were provided in the source data. The vulnerability could allow unauthorized modification of critical certificate management settings, potentially undermining the security posture of the affected Ivanti products and the networks they protect.

For European organizations using Ivanti Connect Secure or Ivanti Policy Secure, this vulnerability poses a significant risk to the integrity and confidentiality of their network security configurations. Since Ivanti products are commonly used for secure remote access and VPN services, unauthorized modification of certificate management settings could lead to weakened authentication mechanisms, unauthorized access, or interception of sensitive communications. This could result in data breaches, disruption of secure remote access services, and potential lateral movement within corporate networks. The requirement for authenticated admin access with read-only rights means insider threats or compromised admin credentials could be leveraged to exploit this vulnerability. Given the critical role of these products in securing remote connections, especially in the context of increased remote work in Europe, exploitation could impact business continuity and compliance with data protection regulations such as GDPR. While no active exploits are currently known, the medium severity and ease of exploitation with low complexity suggest that attackers may develop exploits, increasing risk over time.

European organizations should prioritize upgrading Ivanti Connect Secure to version 22.7R2.8 or later and Ivanti Policy Secure to version 22.7R1.5 or later as soon as patches become available. Until patches are applied, organizations should audit and restrict admin accounts with read-only privileges, ensuring that only trusted personnel have such access. Implementing strict multi-factor authentication (MFA) for all administrative access can reduce the risk of credential compromise. Network segmentation should be enforced to limit access to the management interfaces of Ivanti products. Monitoring and logging of administrative actions should be enhanced to detect unauthorized configuration changes promptly. Additionally, organizations should review certificate management policies and verify the integrity of critical settings regularly. If possible, temporarily disable or restrict remote administrative access to the certificate management component until the vulnerability is remediated. Finally, organizations should stay informed about vendor advisories for any updated patches or mitigation guidance.
