CVE-2025-33005 is a medium-severity vulnerability identified in IBM Planning Analytics Local versions 2.0 and 2.1. The issue stems from insufficient session expiration controls, specifically the failure to invalidate user sessions upon logout. This vulnerability is classified under CWE-613, which pertains to insufficient session expiration. In practical terms, after a user logs out, the session token or session context remains valid and active, allowing an authenticated user to reuse or hijack the session to impersonate another user on the system. Since the vulnerability requires the attacker to be authenticated (PR:L) and does not require user interaction (UI:N), it implies that an attacker with some level of access could exploit this flaw to escalate privileges or access unauthorized data by leveraging stale sessions. The CVSS v3.1 base score is 6.3, indicating a medium severity level, with the vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L, meaning the attack can be performed remotely over the network with low complexity, requires low privileges, no user interaction, and impacts confidentiality, integrity, and availability to a limited extent. No known exploits are reported in the wild yet, and no patches are currently linked, suggesting that organizations using these versions should prioritize mitigation and monitoring. The vulnerability could lead to unauthorized access, data leakage, and potential manipulation of analytics data or configurations within IBM Planning Analytics Local environments.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on IBM Planning Analytics Local for critical financial planning, budgeting, and forecasting operations. Unauthorized session reuse could allow malicious insiders or attackers who have gained low-level access to escalate privileges, impersonate higher-privileged users, and access sensitive financial data or manipulate analytics results. This could lead to data breaches, financial misreporting, and compliance violations under regulations such as GDPR, which mandates strict controls on personal and financial data. Additionally, the integrity of business intelligence and planning data could be compromised, affecting decision-making processes. The availability impact is limited but could manifest if attackers disrupt sessions or cause denial of service through session misuse. Since IBM Planning Analytics is used in sectors like finance, manufacturing, and retail, the risk extends to critical business functions. The medium severity suggests that while the threat is not immediately critical, it requires timely attention to prevent potential exploitation.

European organizations should implement the following specific mitigations: 1) Immediately review and enforce session management policies within IBM Planning Analytics Local, including manual session invalidation where possible. 2) Restrict access to the IBM Planning Analytics Local environment to trusted networks and users, employing network segmentation and zero-trust principles. 3) Monitor session activity logs for anomalies such as multiple concurrent sessions from the same user or sessions persisting beyond logout events. 4) Apply strict authentication controls, including multi-factor authentication (MFA), to reduce the risk of unauthorized authenticated access. 5) Regularly update and patch IBM Planning Analytics Local once IBM releases a fix for this vulnerability. 6) Educate users about secure logout practices and the risks of session reuse. 7) Consider implementing additional session timeout controls at the web server or application gateway level to forcibly expire sessions after logout or inactivity. 8) Conduct periodic security assessments and penetration testing focused on session management to identify and remediate similar issues proactively.
