CVE-2022-37884
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 exists in the ClearPass Policy Manager Guest User Interface that can allow an unauthenticated attacker to send specific operations which result in a Denial-of-Service condition. A successful exploitation of this vulnerability results in the unavailability of the guest interface in Aruba ClearPass Policy Manager version(s): 6.10.x: 6.10.6 and below; 6.9.x: 6.9.11 and below. Aruba has released upgrades for Aruba ClearPass Policy Manager that address this security vulnerability.

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 installed ClearPass Policy Manager versionAccess the ClearPass admin UI and navigate to Administration > Agents and Software Updates > Software Catalog, or use the CLI command 'show version' to determine the exact version numberAffected if The installed version falls within 6.9.0 to 6.9.11 or 6.10.0 to 6.10.6
-
Verify Guest User Interface module statusIn the ClearPass admin UI, go to Configuration > Guest User Management or check Services > Guest to confirm the guest interface functionality is enabledAffected if The Guest User Interface module is enabled on the system
-
Confirm network exposure of guest interfaceReview network accessibility of the guest portal by checking the service listener configuration or firewall rules - determine if the guest interface (typically port 443 or 8080) is exposed to unauthenticated network accessAffected if The guest interface is reachable by unauthenticated attackers from the network
You are affected if your ClearPass Policy Manager runs version 6.9.x below 6.9.12 or 6.10.x below 6.10.7, the Guest User Interface is enabled, and it is accessible to unauthenticated attackers.
