Security readout for executives and security teams
Plain-English summary
Dell EMC Integrated Data Protection Appliance before version 2.3 did not limit authentication attempts against the ACM API. This can let a remote attacker repeatedly try credentials and potentially gain system access. Because IDPA protects backup and recovery infrastructure, compromise could affect sensitive data and operational resilience.
Executive priority
Treat this as high-priority if Dell EMC IDPA is present. Backup infrastructure compromise can undermine recovery during incidents, and the issue is rated critical. Patch or formally risk-accept affected appliances after validating exposure.
Technical view
CVE-2019-3746 is CWE-307: improper restriction of excessive authentication attempts in the Dell EMC IDPA ACM API. Affected versions are prior to 2.3. The CVSS 3.0 score is 9.8 with network access, low complexity, no user interaction, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to Dell EMC Integrated Data Protection Appliance deployments running versions prior to 2.3, especially where the ACM API is reachable by remote users or administrative networks.
Exploitation context
The provided sources do not report known active exploitation, and the CVE is not marked KEV. The source text describes brute-force authentication risk. There is a minor evidence tension: the description says authenticated remote user, while CVSS lists no privileges required.
Researcher notes
Do not assume exploit activity from these sources. Focus validation on product/version inventory, ACM API reachability, and authentication-failure telemetry. Use Dell’s advisory as the authoritative remediation source because the source bundle does not include detailed mitigation mechanics.
Mitigation direction
- Identify all Dell EMC IDPA appliances and record their exact versions.
- Upgrade affected IDPA deployments to version 2.3 or later, per Dell guidance.
- Review Dell DSA-2019-112 for vendor-specific remediation details.
- Prioritize administrative interfaces that are reachable from broader networks.
Validation and detection
- Confirm no IDPA appliance remains on a version prior to 2.3.
- Verify the ACM API is not broadly reachable beyond intended administrators.
- Review authentication logs for repeated failed ACM API login attempts.
- Check vulnerability management records for CVE-2019-3746 closure evidence.

Improper Restriction of Excessive Authentication Attempts
Improper Restriction of Excessive Authentication Attempts represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
