CVE-2025-14810 is a vulnerability classified under CWE-613 (Insufficient Session Expiration) affecting IBM InfoSphere Information Server versions 11.7.0.0 through 11.7.1.6. The core issue is that when a user's privileges are modified during an active session, the system fails to invalidate or refresh the session token accordingly. This means that an authenticated user who had higher privileges before the change can continue to access sensitive information or perform actions beyond their current authorization level. The vulnerability is exploitable remotely over the network (AV:N) with low attack complexity (AC:L), requiring the attacker to have some privileges (PR:L) but no user interaction (UI:N). The scope is unchanged (S:U), and the impact affects confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L). This flaw could lead to unauthorized data exposure or modification if an attacker exploits the stale session. IBM has published this vulnerability with a CVSS score of 6.3, indicating a medium severity level. No patches or exploits are currently documented, but the risk remains significant for environments relying on session-based access controls without proper session invalidation mechanisms.

The vulnerability allows authenticated users to retain access to sensitive data or perform unauthorized actions after their privileges have been reduced, potentially leading to unauthorized disclosure or modification of information. This undermines the principle of least privilege and session security, increasing the risk of insider threats or privilege escalation abuse. For organizations, this could result in data breaches, compliance violations, and damage to reputation. Since IBM InfoSphere Information Server is widely used for data integration and governance in large enterprises, the impact could affect critical business processes and sensitive data handling. The medium severity score reflects that while the vulnerability requires some level of authentication, the ease of exploitation and potential for unauthorized access make it a notable risk. The absence of known exploits reduces immediate threat but does not eliminate the risk of future attacks.

Organizations should immediately review and apply any available patches or updates from IBM once released. In the absence of patches, implement compensating controls such as enforcing shorter session timeouts and requiring re-authentication after privilege changes. Monitor user sessions actively for unusual access patterns, especially after privilege modifications. Employ strict access control policies and audit logs to detect and respond to unauthorized access attempts. Consider integrating multi-factor authentication to reduce the risk of compromised credentials being exploited. Additionally, review and harden session management mechanisms to ensure sessions are invalidated or refreshed upon any change in user privileges. Regularly train administrators and users on secure session handling practices and privilege management.
