CVE-2025-36376 affects IBM Security QRadar EDR versions 3.12 through 3.12.23. The vulnerability stems from the application's failure to invalidate sessions after expiration, classified under CWE-613 (Insufficient Session Expiration). This flaw has 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), indicating medium severity with network accessibility, low attack complexity, and low privileges required.

An authenticated user with low privileges can exploit this issue remotely over the network without user interaction. By continuing to use an expired session token belonging to another user, the attacker can impersonate that user, potentially gaining unauthorized access to limited confidential data, modifying system resources, or disrupting low-level availability.

IBM has published a security advisory at https://www.ibm.com/support/pages/node/7260390 providing details on the vulnerability and remediation steps. Security practitioners should consult this bulletin for patch availability and mitigation guidance specific to affected QRadar EDR deployments.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-12 Session Termination good match

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.

PR.AA-01 mostly match
prevents

Credential lifecycle management directly includes enforcing session expiration to prevent reuse.

PR.AA-05 mostly match
prevents

Authorization policy enforcement and review covers terminating stale sessions to limit access scope.

PR.AA-03 partial match

Authentication mechanisms can incorporate session timeout checks but do not inherently address expiration policy.

A.8.5 Secure authentication none match

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