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
Exploitation of Authorization vulnerability in the web interface in McAfee Network Security Management (NSM) before 8.2.7.42.2 allows authenticated users to gain elevated privileges via a crafted HTTP request parameter.

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 confidence

This is an authorization/privilege escalation vulnerability in McAfee NSM's web interface. An authenticated user can craft HTTP request parameters to elevate their privileges beyond what their assigned role should permit. The vulnerability stems from insufficient authorization checks in the web application's request handling logic.

MitigationUpgrade McAfee NSM to version 8.2.7.42.2 or later to obtain the vendor patch. If immediate patching is not feasible, restrict web interface access to trusted users only and monitor for unusual administrative activity.

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 McAfee NSM installation version
    Access the NSM administrative interface or check the product version information through the system console. Locate the version number displayed in the product's about or system information section.
    Affected if The installed version is lower than 8.2.7.42.2 (any version < 8.2.7.42.2 is affected)
  2. Verify web interface is enabled
    Confirm that the NSM web interface service is running and accessible. Check if the web-based administrative console is currently active.
    Affected if The web interface is enabled and accessible to users - this is the attack vector for the vulnerability
  3. Review user role assignments
    Examine the NSM user management console to see which users are assigned to non-administrative roles. Identify accounts that have limited privileges but may have accessed the system.
    Affected if Non-administrative user accounts exist in the system who could potentially exploit the privilege escalation
  4. Audit recent administrative activity
    Inspect NSM logs or audit trails for any administrative actions performed by users who should only have standard or limited privileges. Look for configuration changes, policy modifications, or system settings altered by accounts without elevated permissions.
    Affected if Any administrative actions were performed by users whose assigned role should not permit such operations

You are affected if your NSM version is below 8.2.7.42.2 and the web interface is accessible to authenticated users who could attempt privilege escalation.
