Security readout for executives and security teams
Plain-English summary
CVE-2021-21512 is a high-severity information disclosure issue in Dell EMC PowerProtect Cyber Recovery 19.7.0.1. A highly privileged local Cyber Recovery user could potentially use it to take over the configured notification email account, creating risk to operational alerts and account integrity.
Executive priority
Treat this as a priority for environments using PowerProtect Cyber Recovery 19.7.0.1, especially where privileged administrator access is broad. Business risk centers on compromised recovery notification email and loss of trust in operational alerting.
Technical view
The CVE describes CWE-200 in Dell EMC PowerProtect Cyber Recovery 19.7.0.1. CVSS 3.1 is 7.9: local attack vector, low complexity, high privileges required, no user interaction, changed scope, high confidentiality and integrity impact, and no availability impact.
Likely exposure
Exposure appears limited to organizations running Dell EMC PowerProtect Cyber Recovery 19.7.0.1 with users who have high-privileged local Cyber Recovery access. The source bundle does not identify broader affected versions.
Exploitation context
The bundle does not show CISA KEV listing or other cited evidence of active exploitation. Exploitation requires local access and high privileges, but the impact can extend beyond the application by compromising the notification email account.
Researcher notes
Evidence is narrow: the bundle names version 19.7.0.1, CWE-200, and a high-privileged local user path. It does not provide exploit details, active exploitation evidence, or confirmed fixed versions. Validate against Dell’s advisory before expanding scope.
Mitigation direction
- Inventory PowerProtect Cyber Recovery deployments and identify any 19.7.0.1 instances.
- Review Dell advisory DSA-2021-038 for fixed versions or vendor mitigation guidance.
- Restrict high-privileged Cyber Recovery access to trusted administrators only.
- Rotate notification email account credentials if exposure is plausible.
- Monitor the notification email account for unauthorized sign-ins or changes.
Validation and detection
- Confirm the installed PowerProtect Cyber Recovery version on each deployment.
- Verify whether any deployment is running version 19.7.0.1.
- Review high-privileged Cyber Recovery user assignments for unnecessary access.
- Check notification email account logs for suspicious activity.
- Document vendor advisory status and remediation evidence.
