CVE-2019-13517
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 · uneditedIn Pyxis ES Versions 1.3.4 through to 1.6.1 and Pyxis Enterprise Server, with Windows Server Versions 4.4 through 4.12, a vulnerability has been identified where existing access privileges are not restricted in coordination with the expiration of access based on active directory user account changes when the device is joined to an AD domain.
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 confidencePyxis ES and Pyxis Enterprise Server devices joined to an AD domain fail to re-validate user account status (enabled/disabled/expired) after initial authentication, allowing users whose AD accounts have been disabled, expired, or removed to retain access based on cached credentials.

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 installed Pyxis productLocate the product name and version in the system administration console or check the installed software inventory for either 'Bd Pyxis Enterprise Server' or 'Bd Pyxis Es'Affected if The product is either Bd Pyxis Enterprise Server or Bd Pyxis Es
-
Verify the version is within affected rangeCompare your installed version against the affected ranges: Bd Pyxis Enterprise Server 4.4 to 4.12, or Bd Pyxis ES 1.3.4 to 1.6.1Affected if The installed version falls within or includes 4.4-4.12 for Enterprise Server or 1.3.4-1.6.1 for ES
-
Confirm Active Directory integration is enabledCheck the system configuration or authentication settings to determine if the device is configured to use Active Directory for user authenticationAffected if The device is joined to an AD domain and uses AD authentication
-
Verify credential caching behaviorInspect the authentication or session management settings to confirm that credentials are cached after initial login without periodic re-validation of AD account statusAffected if The system caches AD credentials and does not re-check account status (enabled/disabled/expired) on subsequent access requests
You are affected if you are running a version in the affected ranges AND the device is joined to an AD domain with cached credentials that are not re-validated against current AD account status.

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 dataImplement real-time validation of AD account status on each access request and terminate sessions immediately upon detection of account changes, expiration, or disablement.
