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
On N-central, it is possible for any authenticated user to read, write and modify syslog configuration across customers on an N-central server. This vulnerability is present in all deployments of N-central prior to 2025.2.

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 bypass vulnerability in N-central where any authenticated user (regardless of their role or customer assignment) can read, write, and modify syslog configuration for all customers on the server. This breaks multi-tenant isolation by allowing cross-customer syslog configuration access.

MitigationUpgrade N-central to version 2025.2 or later. Review access logs for unauthorized syslog configuration changes and verify that customer data isolation is functioning correctly post-patch.

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. Check installed N-central version
    Access the N-central administration console and navigate to System > License or About section to view the current version number
    Affected if The displayed version is earlier than 2025.2 (e.g., 2025.1, 2024.x, or earlier)
  2. Identify user role assignments
    Navigate to Users and Roles management in N-central. Review the role assigned to each user account and note which customers or organizations each role is permitted to access
    Affected if Any user account exists with a role that is assigned to more than one customer organization, as this enables the cross-tenant access vector
  3. Test syslog configuration access scope
    Log in as a standard authenticated user with limited customer access. Attempt to navigate to or query syslog configuration settings for a different customer organization than the one assigned to your account
    Affected if You can successfully view, modify, or export syslog configuration for customers outside your assigned scope, indicating the authorization bypass is present
  4. Review audit logs for cross-customer syslog activity
    Examine N-central audit or access logs for syslog configuration events (create, read, update, delete) where the acting user account belongs to a different customer than the target syslog configuration
    Affected if Logs show syslog configuration changes performed by users accessing customer organizations they are not assigned to
  5. Verify multi-tenant isolation in syslog settings
    As an administrator, check if the syslog configuration UI enforces customer boundaries by restricting users to only see and modify syslog settings for their own customer organization
    Affected if The syslog configuration interface fails to enforce customer boundaries, allowing any authenticated user to manage syslog for all customers on the server

The environment is affected if N-central version is earlier than 2025.2 and any authenticated user can access syslog configuration for customers outside their assigned organization.

Upgrade available Upgrade to 2025.2 or later
Fixed in 2025.2
Interim mitigation

Upgrade N-central to version 2025.2 or later. Review access logs for unauthorized syslog configuration changes and verify that customer data isolation is functioning correctly post-patch.

Recommended fix High confidence

2025.2

  1. Obtain the N-central 2025.2 upgrade package from the official N-able customer portal or download center
  2. Review the N-central 2025.2 release notes for any pre-upgrade requirements or migration steps
  3. Ensure you have a complete backup of the N-central server and database before proceeding
  4. Follow the standard N-central upgrade procedure as documented in the official N-able documentation at documentation.n-able.com
  5. After upgrade, verify that the syslog configuration access control vulnerability is resolved by testing cross-customer syslog access restrictions
