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 · unedited
An access control vulnerability was found, due to the restrictions that are applied on actual assertions not being enforced in their debug functionality. An authenticated user with reduced visibility can obtain unauthorized information via the debug functionality, obtaining data that would normally be not accessible in the Query and Assertions functions.

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 confidence

This is an access control bypass vulnerability in the debug functionality. Authenticated users with reduced visibility/permissions can access data through debug features that do not enforce the same access restrictions as the normal Query and Assertions functions, allowing unauthorized information disclosure.

MitigationEnsure debug functionality enforces the same access control restrictions as the Query and Assertions functions, restricting data access based on user permissions.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed product and version
    Determine if Nozomi Networks CMC or Guardian is installed, and note the exact version number from the system
    Affected if The installed version is lower than 22.6.2 for either product
  2. Locate debug functionality access point
    Identify how debug features are accessed in the Nozomi interface (typically through a debug mode, diagnostic endpoint, or special URL parameter)
    Affected if Debug functionality is accessible in the current installation
  3. Test access control enforcement on debug features
    Using an account with reduced visibility or limited permissions, attempt to access data through debug features that normally require higher privileges
    Affected if A lower-privilege authenticated user can retrieve data through debug features that would be restricted through the standard Query or Assertions functions
  4. Compare debug vs normal function access controls
    Verify whether debug features enforce the same permission checks as the Query and Assertions functions when accessed by users with limited visibility
    Affected if Debug features allow data access that would be denied through the normal Query/Assertions interface for the same user

A user is affected if the installed Nozomi Networks CMC or Guardian version is below 22.6.2 AND debug functionality is accessible to authenticated users with reduced permissions, allowing them to bypass access restrictions that apply to the standard Query and Assertions features.

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 · scoped
Upgrade available Upgrade to 22.6.2 or later
Fixed in 22.6.2
Interim mitigation

Ensure debug functionality enforces the same access control restrictions as the Query and Assertions functions, restricting data access based on user permissions.

Recommended fix Moderate confidence

CMC and Guardian version 22.6.2 or later

  1. Upgrade CMC (Quantum) to version 22.6.2 or later
  2. Upgrade Guardian to version 22.6.2 or later
  3. After upgrade, verify that debug functionality now properly enforces assertion-based access controls
  4. Confirm that users with reduced visibility can no longer access unauthorized data through debug functionality
