CVE-2025-36379 is a medium-severity Inadequate Encryption Strength (CWE-326) vulnerability in Ibm Qradar Edr. Its CVSS base score is 5.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 4th 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 SC-13 (Cryptographic Protection) and SC-12 (Cryptographic Key Establishment and Management) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-36379 affects IBM Security QRadar EDR versions 3.12 through 3.12.23, specifically the IBM Security ReaQta component. The vulnerability stems from the use of weaker than expected cryptographic algorithms, classified under CWE-326 (Inadequate Encryption Strength). Published on 2026-02-17, it has a CVSS v3.1 base score of 5.9 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating medium severity with high confidentiality impact but no integrity or availability effects.
An unauthenticated attacker with network access could exploit this vulnerability, though it requires high attack complexity and no user interaction. Successful exploitation would allow the attacker to decrypt highly sensitive information protected by the weak algorithms.

Mitigating Controls (NIST 800-53 r5) AI
SC-13 requires selection and implementation of specific cryptographic algorithms and key lengths, directly preventing use of inadequate encryption strength.
SC-12 governs cryptographic key establishment and management, which can enforce sufficient key sizes and thereby reduce inadequate encryption strength.
