CVE-2021-22497
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 · uneditedAdvanced Authentication versions prior to 6.3 SP4 have a potential broken authentication due to improper session management issue.
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 confidenceAdvanced Authentication versions before 6.3 SP4 contain a broken authentication vulnerability caused by improper session management, allowing attackers to potentially hijack user sessions or bypass authentication controls.

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.
-
Confirm Netiq Advanced Authentication is installedLocate the product in your system's installed programs or services list, looking for 'Netiq Advanced Authentication' or 'Microfocus Netiq Advanced Authentication'Affected if The product is found installed on the system
-
Determine the installed versionAccess the product's administrative interface, registry entries, or version information file to retrieve the exact version number of Advanced AuthenticationAffected if The version is 6.3 or any version below 6.3 (e.g., 6.2.x, 6.1.x, etc.)
-
Identify if the session management component is activeCheck whether the Advanced Authentication service is running and serving authentication sessions - inspect the authentication service status or active session configurationsAffected if The service is active and handling user authentication sessions, which is the default state for a deployed authentication server
-
Review session configuration for the vulnerability patternInspect the Advanced Authentication session management settings for improper session token handling, checking for predictable session IDs or lack of proper session invalidation on logoutAffected if Session tokens are not properly randomized or session state is not invalidated upon logout, indicating the broken session management is present
You are affected if Netiq Advanced Authentication version 6.3 or any version below 6.3 is installed and the authentication service is active, as the improper session management vulnerability exists in these versions.
