Security readout for executives and security teams
Plain-English summary
CVE-2021-20396 is an information disclosure issue in IBM QRadar Analyst Workflow App versions 1.0 through 1.18.0. The app can store web pages locally, allowing another local system user to read them. Impact appears limited, but QRadar may contain sensitive security investigation context.
Executive priority
Treat as a moderate-priority confidentiality issue. It is not presented as remotely exploitable, but affected QRadar systems may expose sensitive security operations data to local users.
Technical view
The CVE describes local, unauthenticated confidentiality exposure with CVSS 3.0 score 4.0: AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N. IBM X-Force ID 196009 maps it to QRadar Analyst Workflow App 1.0 through 1.18.0. The supplied evidence does not identify remote, integrity, or availability impact.
Likely exposure
Exposure is likely limited to IBM QRadar SIEM environments with the QRadar Analyst Workflow App installed in versions 1.0 through 1.18.0.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation evidence. The CVSS vector indicates local access is required and confidentiality impact is low.
Researcher notes
Evidence is sparse: no CWE, exploit details, or specific fixed version is included in the supplied bundle. Validation should focus on product presence, version range, local user access, and IBM’s advisory.
Mitigation direction
- Inventory QRadar Analyst Workflow App deployments and versions.
- Review IBM advisory for supported remediation or upgrade guidance.
- Prioritize systems where QRadar stores sensitive investigations or regulated data.
- Restrict local system access to trusted administrative users.
Validation and detection
- Confirm whether QRadar Analyst Workflow App is installed.
- Record the installed app version and compare against 1.0 through 1.18.0.
- Check IBM advisory and X-Force entry for current remediation status.
- Review local user access on affected QRadar systems.
