CVE-2019-3746
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDell EMC Integrated Data Protection Appliance versions prior to 2.3 do not limit the number of authentication attempts to the ACM API. An authenticated remote user may exploit this vulnerability to launch a brute-force authentication attack in order to gain access to the system.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceDell EMC Integrated Data Protection Appliance versions prior to 2.3 lack rate limiting on the ACM API authentication endpoint, allowing an authenticated remote attacker to make unlimited login attempts and perform brute-force attacks against other accounts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check the Integrated Data Protection Appliance firmware versionAccess the appliance management interface or CLI to view system version information. Look for the firmware version in the system status or about section.Affected if The installed version is 2.0, 2.1, or 2.2 (versions prior to 2.3)
-
Verify rate limiting configuration on the ACM API authentication endpointAccess the ACM API configuration settings through the appliance administrative interface. Check if rate limiting, request throttling, or authentication attempt limiting is enabled for the authentication endpoint.Affected if Rate limiting is not configured or is disabled on the ACM API authentication endpoint
-
Review API authentication logs for anomalous patternsExamine the ACM API or authentication logs for repeated login attempts from a single source, multiple failed attempts across different accounts, or unusually high authentication request volumes.Affected if Logs contain patterns indicative of brute-force or unlimited authentication attempts
If the firmware version is 2.0, 2.1, or 2.2 and no rate limiting is enforced on the ACM API authentication endpoint, the environment is affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to version 2.3 or later which implements authentication attempt limiting. Until patched, monitor API logs for anomalous authentication patterns and consider network-level rate limiting as a temporary control.
