CVE-2021-22509
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 identified in storing and reusing information in Advance Authentication. This issue can lead to leakage of sensitive data to unauthorized user. The issue affects NetIQ Advance Authentication before 6.3.5.1
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 · moderate confidenceNetIQ Advance Authentication before version 6.3.5.1 has a vulnerability in how it stores and reuses information, allowing sensitive authentication data to be exposed to unauthorized users through improper data handling.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 NetIQ Advance Authentication installationLocate the NetIQ Advance Authentication installation directory or check the installed software on the system using system inventory tools, package managers, or the application's About/Version panel in the management consoleAffected if The product is installed and no version can be determined
-
Determine installed version numberCheck the version of NetIQ Advance Authentication by examining the application's version information, which is typically available in the management console, installer properties, or via command-line tools provided by the productAffected if The version cannot be verified or retrieved
-
Compare version against affected rangeCompare the installed version to the affected ranges: versions < 6.3 and version 6.3 (including 6.3.0 through 6.3.4). If the version is 6.3.5.1 or later, the environment is not affected by this specific CVEAffected if The installed version is less than 6.3, or equals 6.3 (any 6.3.x version before 6.3.5.1)
-
Assess multi-tenant or shared configurationReview the authentication data storage configuration and access control settings, particularly in environments where multiple tenants or users share authentication infrastructureAffected if The product stores authentication data in a shared or multi-tenant configuration without proper data isolation
The environment is affected if NetIQ Advance Authentication version is less than 6.3 or equals 6.3 (any 6.3.x version before 6.3.5.1) and handles sensitive authentication data in a shared or multi-tenant setup.

dbcve · scoped6.3
Upgrade to NetIQ Advance Authentication version 6.3.5.1 or later. Review and audit access controls to stored authentication data and implement proper data isolation for multi-tenant or shared authentication scenarios.
6.3.5.1
- Back up the current NetIQ Advanced Authentication configuration and database before initiating the upgrade
- Review the NetIQ Advanced Authentication 6.3.5.1 release notes and upgrade documentation for any specific prerequisites
- Ensure the target environment meets the system requirements for version 6.3.5.1
- Stop all NetIQ Advanced Authentication services on the affected server(s)
- Run the installer or apply the upgrade package for version 6.3.5.1
- Verify the upgrade completed successfully by checking the version number in the administration console
- Confirm that the sensitive data leakage vulnerability (CWE-312) is resolved by testing authentication workflows
