CVE-2017-5184
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 · uneditedA vulnerability was discovered in NetIQ Sentinel Server 8.0 before 8.0.1 that may allow leakage of information (account enumeration).
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 · low confidenceAccount enumeration vulnerability in NetIQ Sentinel Server 8.0 before 8.0.1 allows attackers to determine valid user accounts through differential responses from authentication or account-related endpoints.

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 Sentinel Server versionDetermine the installed version of NetIQ Sentinel or Microfocus Sentinel. This is typically accessible via the product's About page, installation files, or version reporting mechanism.Affected if The installed version is 8.0.0 or any 8.0.x version prior to 8.0.1
-
Test login endpoint with invalid usernameSubmit an authentication request to the login endpoint using a clearly invalid username that does not exist in the system. Record the HTTP status code, error message text, and response characteristics.Affected if The response indicates the account does not exist or provides specific feedback about invalid username
-
Test login endpoint with valid usernameSubmit an authentication request using a known valid username but incorrect password. Record the response.Affected if The response differs from the invalid username attempt (different error message, status code, or timing that reveals the account is valid)
-
Compare account enumeration response patternsRepeat tests with multiple known and unknown usernames across authentication and password recovery endpoints. Document any patterns that allow determination of account validity.Affected if Differential responses consistently reveal which usernames are valid in the system
Environment is affected if running Sentinel version 8.0 through 8.0.0 AND authentication or account-related endpoints return different responses for valid versus invalid usernames.

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 data8.0.1
Implement consistent response messaging for authentication and account-related functions regardless of whether the account exists, preventing enumeration of valid usernames.
