Ibm Qradar Edr 3.12.0 – 3.12.24
Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:LSummary
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.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-12 directly requires automatic session termination after a defined period, structurally preventing reuse of expired session identifiers.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Credential lifecycle management directly includes enforcing session expiration to prevent reuse.
Authorization policy enforcement and review covers terminating stale sessions to limit access scope.
Authentication mechanisms can incorporate session timeout checks but do not inherently address expiration policy.

Automatic termination of inactive sessions and limits on connection duration shrink the window during which a hijacked or unattended authenticated session can be exploited.
