CVE-2022-29084
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 Unity, Dell UnityVSA, and Dell Unity XT versions before 5.2.0.0.5.173 do not restrict excessive authentication attempts in Unisphere GUI. A remote unauthenticated attacker may potentially exploit this vulnerability to brute-force passwords and gain access to the system as the victim. Account takeover is possible if weak passwords are used by users.
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 Unity storage systems running versions before 5.2.0.0.5.173 lack rate limiting on the Unisphere GUI login page, allowing unlimited authentication attempts from a single source. This enables remote unauthenticated attackers to perform brute-force password attacks against valid user accounts, leading to potential account takeover.

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.
-
Identify the Dell Unity system versionAccess the Unisphere GUI and navigate to the About or Settings page to view the Operating Environment version, or use the service CLI command 'version' or 'unisphere -version' if availableAffected if The displayed version is any build earlier than 5.2.0.0.5.173 (for example, 5.1.x.x or 5.0.x.x)
-
Confirm Unisphere GUI is accessibleVerify that the Unisphere web interface is reachable over HTTPS/HTTP on the management network by accessing the login page URLAffected if The Unisphere login page is accessible from a network location (even if only internally)
-
Check if authentication rate limiting is enforcedAttempt multiple failed login attempts from a single source IP address against the Unisphere login page using a test account or monitoring login logsAffected if There is no account lockout or rate limiting after repeated failed attempts (no captcha, no temporary lockout, no IP-based throttling)
You are affected if your Dell Unity system runs a version earlier than 5.2.0.0.5.173 and the Unisphere GUI is accessible, with no rate limiting enforced on login attempts.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped5.2.0.0.5.173
Apply Dell vendor patch 5.2.0.0.5.173 or later to implement account lockout and rate limiting. Enforce strong password policies as defense-in-depth while patching.
Unity Operating Environment 5.2.0.0.5.173 or later (including Unity XT and UnityVSA)
- 1. Back up all critical data and configurations from the current Unity system
- 2. Review Dell Unity 5.2.0.0.5.173 release notes for any pre-upgrade requirements
- 3. Schedule a maintenance window as the upgrade may require system downtime
- 4. Download Dell Unity Operating Environment version 5.2.0.0.5.173 or later from Dell Support (support.dell.com)
- 5. Apply the upgrade following Dell's official upgrade procedure for your specific Unity model
- 6. Verify the upgrade was successful by checking the Unisphere GUI version information
- 7. Confirm the authentication attempt lockout feature is now enforced in Unisphere settings
