CVE-2025-5463 is a vulnerability classified under CWE-532, which involves the insertion of sensitive information into log files within Ivanti Connect Secure and Ivanti Policy Secure products. Specifically, versions prior to 22.7R2.8 for Connect Secure and 22.7R1.5 for Policy Secure are affected. This vulnerability allows a local authenticated attacker to access sensitive data that is improperly logged by the system. The vulnerability arises because sensitive information, potentially including credentials or session tokens, is recorded in log files without adequate protection or redaction. Since the attacker must have local authenticated access, the threat actor needs to have some level of legitimate access to the system, but no user interaction is required beyond that. The CVSS v3.1 base score is 5.5 (medium severity), with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N indicating that the attack requires local access with low complexity, privileges, and no user interaction, and impacts confidentiality with high severity but does not affect integrity or availability. There are no known exploits in the wild at the time of publication, and no patch links were provided, suggesting that remediation may require updating to fixed versions or applying vendor guidance once available. The vulnerability primarily threatens confidentiality by exposing sensitive information through logs accessible to authenticated users who should not have access to such data. This can facilitate further attacks or unauthorized data disclosure if logs are accessed or exfiltrated by malicious insiders or attackers who have gained local access.

For European organizations using Ivanti Connect Secure or Ivanti Policy Secure, this vulnerability poses a significant risk to the confidentiality of sensitive information. These products are often used to provide secure remote access and policy enforcement, making them critical components in enterprise network security. Exposure of sensitive data in logs could lead to credential theft, session hijacking, or leakage of internal network details, which in turn can facilitate lateral movement or privilege escalation within the organization. Given the requirement for local authenticated access, the threat is particularly relevant in environments where multiple users have access to the management interfaces or where insider threats are a concern. The impact is heightened in sectors with strict data protection regulations such as GDPR, where unauthorized disclosure of personal or sensitive data can result in regulatory penalties and reputational damage. Additionally, organizations relying on these Ivanti products for VPN or policy enforcement may face increased risk of compromise if attackers leverage the leaked information to bypass security controls.

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 vendor patches become available. Until patches are applied, organizations should restrict local authenticated access to these systems to only trusted administrators and implement strict access controls and monitoring to detect any unauthorized log access. Reviewing and hardening logging configurations to minimize sensitive data capture is recommended, including disabling verbose logging or redacting sensitive fields if configurable. Employing file integrity monitoring on log files can help detect unauthorized access or tampering. Additionally, organizations should conduct audits of existing logs to identify any sensitive information exposure and securely archive or delete such logs. Implementing multi-factor authentication (MFA) for all administrative access can reduce the risk of unauthorized local access. Finally, educating administrators about the risks of sensitive data exposure in logs and enforcing the principle of least privilege will help mitigate exploitation opportunities.
