IBM InfoSphere Information Server versions 11.7.0.0 through 11.7.1.6 have a vulnerability that permits authenticated users to maintain access to sensitive information even after their privileges are modified. This issue is classified under the Common Weakness Enumeration (CWE) as CWE-613: Insufficient Session Expiration. The CVSS 3.1 base score assigned to this vulnerability is 6.3, indicating a medium severity level.
The vulnerability exists due to the failure to invalidate sessions after privilege changes, which could allow unauthorized access to sensitive data. Organizations utilizing affected versions must recognize the potential risks associated with this vulnerability, as attackers may leverage it to gain unauthorized access.
Given the CVSS score of 6.3, organizations should prioritize addressing this vulnerability in their patch cycles. The risk to organizations includes possible exposure of sensitive information, which can lead to significant reputational damage and regulatory implications.
As of now, there is no known public exploit for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. Organizations are advised to remain vigilant and implement appropriate security measures.
Vulnerability Details
The vulnerability allows attackers to retain access to sensitive information due to insufficient session expiration in IBM InfoSphere Information Server versions 11.7.0.0 through 11.7.1.6. The CVSS 3.1 vector string is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L, and the CWE classification is CWE-613.
The vulnerability was published on March 25, 2026, and remains analyzed. The potential impacts on confidentiality, integrity, and availability are considered low, but the risk of unauthorized access remains a concern.
Technical Analysis
The root cause of this vulnerability is the failure of the application to invalidate user sessions after their privileges are modified. This lack of session management can lead to unauthorized access by users who should no longer have access to certain information.
The attack vector for this vulnerability is classified as network, with a low attack complexity. It requires low privileges to exploit and does not require user interaction. The impacts on confidentiality, integrity, and availability are all rated as low.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant. Organizations that fail to address this issue may find themselves exposed to unauthorized access, potentially leading to data breaches and compliance violations. The medium severity rating indicates that organizations must address this vulnerability in their priority patch cycle.
The potential blast radius of this vulnerability includes all users with modified privileges, making the urgency for remediation moderate. Organizations should consider implementing monitoring solutions to detect any unauthorized access attempts.
