Summary

CVE-2025-36377 is a medium-severity Insufficient Session Expiration (CWE-613) vulnerability in Ibm Qradar Edr. Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Browser Session Hijacking (T1185); ranked at the 8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-12 (Session Termination) — see the control section below for these in your framework.

IBM Security QRadar EDR versions 3.12 through 3.12.23 contain a vulnerability tracked as CVE-2025-36377, where the application fails to invalidate sessions after expiration. This issue, classified under CWE-613 (Insufficient Session Expiration), carries a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L), rated as medium severity. An authenticated user could exploit this flaw to impersonate another user on the system by continuing to use an expired session token.

The attack requires low-privileged authentication (PR:L) and network access (AV:N) with low complexity (AC:L) and no user interaction (UI:N). A malicious low-privileged user could leverage a previously valid but expired session to perform actions as another user, potentially leading to limited impacts on confidentiality, integrity, and availability (C:L/I:L/A:L). The scope remains unchanged (S:U), making it feasible in environments where session management is critical for access control.

IBM has published an advisory at https://www.ibm.com/support/pages/node/7260390 addressing this vulnerability, including details on mitigation and available patches for affected QRadar EDR versions. Security practitioners should review the advisory for upgrade paths beyond version 3.12.23 to invalidate sessions properly and prevent unauthorized impersonation.

Adversaries may take control of preexisting sessions with remote services to move laterally in an environment.
T1539 Steal Web Session Cookie Credential Access
An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials.
