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 · unedited
Dell CloudBoost Virtual Appliance, versions 19.13.0.0 and prior, contains an Improper Restriction of Excessive Authentication Attempts vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to unauthorized access.

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 confidence

Dell CloudBoost Virtual Appliance versions 19.13.0.0 and prior fail to properly restrict excessive authentication attempts, allowing unauthenticated remote attackers to perform unlimited login attempts and potentially guess valid credentials through brute force.

MitigationApply vendor-provided patches or updates to version 19.13.0.0+ which implement proper account lockout thresholds, login attempt rate limiting, or CAPTCHA mechanisms to prevent automated brute force attacks.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed Dell CloudBoost Virtual Appliance version
    Access the appliance administrative interface or use the system information command available in the appliance management console to retrieve the current firmware/software version number.
    Affected if The installed version is 19.13.0.0 or any version prior to 19.13.0.2.
  2. Locate the authentication configuration settings
    Navigate to the appliance security or authentication settings panel within the management console or examine the configuration file that defines login policies.
    Affected if No authentication rate limiting, account lockout threshold, or CAPTCHA enforcement settings are defined or visible in the configuration.
  3. Verify account lockout policy presence
    Check whether the appliance has an account lockout policy configured that limits the number of failed login attempts before an account is temporarily disabled.
    Affected if There is no account lockout policy configured, or failed authentication attempts are not tracked or limited.
  4. Confirm brute force protection mechanisms
    Inspect the login mechanism to determine if there is any rate limiting (such as limiting requests per minute) or CAPTCHA that would prevent automated credential guessing tools.
    Affected if The login interface permits unlimited consecutive failed attempts without any throttling, delay, or challenge response.

You are affected if your Dell CloudBoost Virtual Appliance runs version 19.13.0.0 or prior and lacks rate limiting, account lockout thresholds, or CAPTCHA mechanisms on the authentication interface.

Upgrade available Upgrade to 19.13.0.2 or later
Fixed in 19.13.0.2
Interim mitigation

Apply vendor-provided patches or updates to version 19.13.0.0+ which implement proper account lockout thresholds, login attempt rate limiting, or CAPTCHA mechanisms to prevent automated brute force attacks.

Recommended fix Moderate confidence
