Security QRadar EDR: Inadequate Encryption Strength
CVE-2025-36379 is a high-severity inadequate encryption strength vulnerability in Security QRadar EDR from IBM, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Security QRadar EDR versions: 3.12 through 3.12.23. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.17% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Qradar Edr to 3.12.24 or a later version.
- Read the advisory on ibm.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Inadequate Encryption Strength
The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
How developers prevent this class of flaw
- Use an encryption scheme that is currently considered to be strong by experts in the field.
