Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
IBM Security QRadar 3.12 EDR is affected by CVE-2024-45643, a vulnerability stemming from the use of weaker than expected cryptographic algorithms. This issue, classified under CWE-327 (Broken or Risky Cryptographic Algorithm), enables an attacker to decrypt sensitive credential information stored or transmitted by the product. The vulnerability received 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.
A remote attacker with no privileges or user interaction required can exploit this over the network, though it demands high attack complexity. Successful exploitation allows the attacker to decrypt sensitive credential information, potentially exposing authentication data or other secrets used within QRadar 3.12 EDR environments.
IBM has published a security advisory with details on mitigation at https://www.ibm.com/support/pages/node/7185938. Security practitioners should consult this bulletin for patch availability, workaround guidance, and affected version specifics.

Mitigating Controls (NIST 800-53 r5) AI
SC-13 requires selection and implementation of specific cryptography types, directly stopping use of broken algorithms.

PR.DS-01 promotes encryption for data-at-rest but never requires strong algorithms, leaving CWE-327 fully possible; the weakness is also far broader than data-at-rest so one narrow control removes none of its total risk.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Mandating approved algorithms, cipher strength and usage standards directly stops the selection of broken or weak cryptographic primitives that attackers can exploit.
The explicit call-out of cryptography-related legal constraints (import/export, key escrow, digital-signature validity) reduces the likelihood that an organization will adopt broken or non-compliant cryptographic algorithms that violate those rules.
Access to current specialist guidance and early vulnerability alerts enables timely replacement of broken or risky cryptographic algorithms with stronger alternatives.
