A 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.

Security readout for executives and security teams

Plain-English summary

This flaw can let an unauthenticated attacker make the Aruba ClearPass guest interface unavailable. It does not indicate data theft or system takeover in the provided sources, but it can disrupt guest network onboarding and related access workflows.

Executive priority

Treat this as a high-priority availability risk for ClearPass guest access. Patch exposed or business-critical deployments promptly, especially where guest onboarding outages would affect operations or customer-facing access.

Technical view

CVE-2022-37884 affects the ClearPass Policy Manager Guest User Interface. The CVSS 3.1 vector is network-accessible, low complexity, no privileges, no user interaction, with high availability impact only. The issue is mapped to CWE-400 resource consumption.

Likely exposure

Organizations running Aruba ClearPass Policy Manager 6.10.x through 6.10.6 or 6.9.x through 6.9.11 are exposed if the Guest User Interface is reachable by potential attackers.

Exploitation context

The provided sources describe unauthenticated denial of service through specific operations against the guest interface. They do not state active exploitation, public exploit availability, or CISA KEV listing.

Researcher notes

Evidence is limited to the CVE record and Aruba advisory reference. The source bundle names affected versions and confirms Aruba released upgrades, but does not provide exploit details, indicators of compromise, or compensating controls.

Mitigation direction

  • Upgrade Aruba ClearPass Policy Manager using Aruba's released fixes.
  • Consult Aruba advisory ARUBA-PSA-2022-013 for exact fixed release guidance.
  • Prioritize systems where the guest interface is reachable from untrusted networks.
  • If upgrade is delayed, follow Aruba guidance for interim risk reduction.

Validation and detection

  • Inventory ClearPass Policy Manager instances and record installed versions.
  • Compare versions against 6.10.6 and below, and 6.9.11 and below.
  • Confirm whether the Guest User Interface is enabled and externally reachable.
  • After remediation, verify the installed version is no longer affected.
