Security readout for executives and security teams

Plain-English summary

IBM QRadar Advisor With Watson App can expose sensitive information through HTTP requests. The issue is medium severity because it affects confidentiality only, but the exposed information could help an attacker plan follow-on activity against a QRadar SIEM environment.

Executive priority

Treat as a scheduled remediation item for QRadar environments. It is not described as actively exploited, but QRadar is security-critical infrastructure and information leakage can support later intrusion attempts.

Technical view

CVE-2021-20380 affects IBM QRadar Advisor With Watson App 1.1 through 2.5 as used on IBM QRadar SIEM 7.4. The CVSS 3.0 score is 5.3 with network access, low complexity, no privileges, and no user interaction required. Impact is limited to confidentiality.

Likely exposure

Exposure is limited to organizations running the affected QRadar Advisor With Watson App versions on IBM QRadar SIEM 7.4. The bundle does not specify whether internet exposure is required or which HTTP requests reveal data.

Exploitation context

The CVE is not listed as CISA KEV in the provided bundle. CVSS exploit maturity is unproven, and the provided sources do not claim active exploitation or public exploit availability.

Researcher notes

The available description is sparse: it confirms sensitive information disclosure via HTTP requests but does not identify the exact request path, leaked fields, or fixed release. Avoid assumptions beyond IBM and CVE records.

Mitigation direction

  • Inventory QRadar SIEM 7.4 deployments using QRadar Advisor With Watson App.
  • Check IBM advisory guidance for the supported fixed version or update path.
  • Apply IBM-provided remediation or upgrade for affected app versions.
  • Restrict access to QRadar management and app HTTP interfaces.
  • Review logs for unusual unauthenticated or remote HTTP access patterns.

Validation and detection

  • Confirm installed QRadar Advisor With Watson App version across QRadar SIEM 7.4 systems.
  • Verify whether versions fall within 1.1 through 2.5.
  • Confirm IBM remediation has been applied according to vendor guidance.
  • Review exposure of QRadar HTTP interfaces to untrusted networks.
  • Document compensating controls if immediate remediation is delayed.
