CVE-2023-25591
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 in the web-based management interface of ClearPass Policy Manager could allow a remote attacker authenticated with low privileges to access sensitive information. A successful exploit allows an attacker to retrieve information which could be used to potentially gain further privileges on the ClearPass instance.
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 confidenceClearPass Policy Manager's web-based management interface contains an information disclosure vulnerability allowing authenticated low-privilege users to access sensitive system information that could facilitate privilege escalation. The flaw exists in the interface's access control logic for certain API endpoints or pages.

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 ClearPass Policy Manager installationLocate the ClearPass Policy Manager server and determine its hostname or IP address in your environment inventory or network scan results.Affected if ClearPass Policy Manager is present in your environment
-
Determine installed versionLog into the ClearPass Policy Manager admin UI or check the version via CLI: login and run 'show version' or access About page in the management interface. Compare the version number to affected ranges: 6.9.0-6.9.13, 6.10.0-6.10.8, 6.11.0, or 6.11.1.Affected if Installed version falls within 6.9.0 through 6.9.13, 6.10.0 through 6.10.8, 6.11.0, or 6.11.1
-
Verify web management interface is accessibleConfirm the ClearPass Policy Manager web-based management interface (HTTPS on port 443 or 4433) is reachable and operational.Affected if Web management interface is enabled and accessible on the network
-
Check for low-privilege user accountsReview the ClearPass user database or directory integration to identify authenticated user accounts with low-privilege or operator-level roles.Affected if Low-privilege user accounts exist in the system
-
Inspect API endpoint access with low-privilege sessionUsing a low-privilege user account, attempt to access API endpoints or pages that should be restricted to admin roles. Look for unexpected disclosure of sensitive system configuration, user privilege details, or internal system information.Affected if Low-privilege user can access sensitive system information through API endpoints that should be restricted
Environment is affected if ClearPass Policy Manager versions 6.9.0-6.9.13, 6.10.0-6.10.8, 6.11.0, or 6.11.1 are installed and the web management interface with low-privilege users is accessible.

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.
dbcve · scopedApply the vendor patch from Aruba's security advisory and review user role permissions to ensure least-privilege access controls are properly configured.
