CVE-2025-33005 is a security vulnerability identified in IBM Planning Analytics Local versions 2.0 and 2.1. The vulnerability is classified under CWE-613, which pertains to insufficient session expiration. Specifically, the issue arises because the application does not properly invalidate user sessions upon logout. This flaw allows an authenticated user to potentially impersonate another user on the system by reusing an active session token or session identifier that should have been terminated. The vulnerability has a CVSS 3.1 base score of 6.3, indicating a medium severity level. The attack vector is network-based (AV:N), requires low privileges (PR:L), and does not require user interaction (UI:N). The scope is unchanged (S:U), and the impact affects confidentiality, integrity, and availability to a low to medium extent (C:L/I:L/A:L). The vulnerability could be exploited remotely by an authenticated user who has access to the system, enabling session hijacking or impersonation attacks. Although no known exploits are currently reported in the wild, the flaw represents a significant risk in environments where multiple users share access or where session tokens are not adequately protected. The lack of session invalidation after logout means that session tokens remain valid and can be reused, undermining the security model of user authentication and session management in IBM Planning Analytics Local. This could lead to unauthorized access to sensitive planning and analytics data, manipulation of business intelligence reports, or disruption of analytics services.

For European organizations using IBM Planning Analytics Local 2.0 or 2.1, this vulnerability poses a risk of unauthorized access and potential data breaches. Given that Planning Analytics is often used for financial planning, budgeting, and forecasting, unauthorized session reuse could lead to exposure or manipulation of sensitive financial data, impacting confidentiality and integrity. This could result in regulatory compliance issues under GDPR due to unauthorized data access. Additionally, session hijacking could disrupt business operations or lead to incorrect decision-making based on tampered analytics data. The medium severity rating suggests that while the vulnerability is not trivially exploitable by unauthenticated attackers, the risk remains significant in environments with multiple users or shared workstations. European organizations with strict data protection requirements and those in finance, manufacturing, or government sectors relying on IBM Planning Analytics Local should be particularly vigilant. The absence of known exploits reduces immediate risk but does not eliminate the potential for targeted attacks, especially from insider threats or attackers with some level of access.

To mitigate this vulnerability, organizations should implement the following specific measures: 1) Apply any available patches or updates from IBM as soon as they are released, even though no patch links are currently provided, monitoring IBM security advisories closely. 2) Enforce strict session management policies, including reducing session timeout durations and implementing manual session invalidation mechanisms where possible. 3) Restrict access to IBM Planning Analytics Local to trusted networks and users, employing network segmentation and access controls to limit exposure. 4) Monitor session activity logs for unusual patterns indicative of session reuse or impersonation attempts. 5) Educate users on proper logout procedures and the risks of leaving sessions active on shared or public workstations. 6) Consider implementing multi-factor authentication (MFA) to add an additional layer of security, reducing the impact of session hijacking. 7) Use endpoint security solutions to detect and prevent session token theft or reuse. 8) Regularly audit user accounts and session management configurations to ensure compliance with security policies. These steps go beyond generic advice by focusing on compensating controls and proactive monitoring tailored to the specific nature of the session expiration flaw in IBM Planning Analytics Local.
