CVE-2025-31962 identifies a security vulnerability in HCL BigFix IVR version 4.2 related to insufficient session expiration controls within its Web UI authentication component. Specifically, the session tokens or cookies used to maintain authenticated sessions have excessively long expiration periods, which means that once an attacker gains authenticated access, they can continue to use the session token beyond a reasonable timeframe without re-authentication. This vulnerability falls under CWE-613 (Insufficient Session Expiration), which is a common security weakness where sessions remain valid longer than necessary, increasing the risk of session hijacking or unauthorized prolonged access. The vulnerability requires the attacker to be authenticated and involves user interaction, which limits the ease of exploitation. The CVSS v3.1 base score is 2.0, reflecting low severity due to the limited confidentiality impact and the requirement for high privileges and user interaction. No integrity or availability impacts are noted. No known exploits have been reported in the wild, and no official patches have been released at the time of publication. The vulnerability affects only version 4.2 of BigFix IVR, a product used for endpoint management and automation. The prolonged session expiration could allow attackers to access protected API endpoints for extended periods, potentially leading to unauthorized data exposure or manipulation if combined with other vulnerabilities or insider threats.

For European organizations, this vulnerability poses a risk primarily to confidentiality due to the potential for prolonged unauthorized access to sensitive API endpoints within BigFix IVR. Organizations relying on BigFix IVR 4.2 for endpoint management and automation could face risks of session hijacking or misuse if session tokens are intercepted or stolen. Although the CVSS score is low, the impact could be more significant in environments where privileged accounts are used or where sensitive operational data is accessible via the API. The risk is heightened in sectors with strict compliance requirements around data protection, such as finance, healthcare, and critical infrastructure. Prolonged session validity could also facilitate lateral movement within networks if attackers leverage the session to access additional resources. However, the requirement for authenticated access and user interaction reduces the likelihood of widespread exploitation. The absence of known exploits limits immediate risk, but organizations should proactively address the issue to prevent future incidents.

European organizations should implement the following specific mitigations: 1) Configure and enforce strict session timeout policies within BigFix IVR, reducing session expiration periods to the minimum practical duration. 2) Monitor and audit session activity logs to detect unusual or prolonged sessions that may indicate misuse. 3) Employ multi-factor authentication (MFA) to reduce the risk of unauthorized authentication. 4) Restrict API endpoint access based on least privilege principles and network segmentation to limit exposure. 5) Educate users and administrators about the risks of session persistence and encourage secure session management practices, such as logging out after use. 6) Stay informed about vendor updates and apply patches promptly once available. 7) Consider deploying Web Application Firewalls (WAF) or session management tools that can enforce session expiration policies externally. 8) Regularly review and update security policies related to session management and authentication mechanisms within the organization’s endpoint management infrastructure.
