CVE-2025-7051
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 · uneditedOn 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 confidenceThis 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.

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.
-
Check installed N-central versionAccess the N-central administration console and navigate to System > License or About section to view the current version numberAffected if The displayed version is earlier than 2025.2 (e.g., 2025.1, 2024.x, or earlier)
-
Identify user role assignmentsNavigate 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 accessAffected 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
-
Test syslog configuration access scopeLog 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 accountAffected if You can successfully view, modify, or export syslog configuration for customers outside your assigned scope, indicating the authorization bypass is present
-
Review audit logs for cross-customer syslog activityExamine 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 configurationAffected if Logs show syslog configuration changes performed by users accessing customer organizations they are not assigned to
-
Verify multi-tenant isolation in syslog settingsAs 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 organizationAffected 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.

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 · scoped2025.2
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.
2025.2
- Obtain the N-central 2025.2 upgrade package from the official N-able customer portal or download center
- Review the N-central 2025.2 release notes for any pre-upgrade requirements or migration steps
- Ensure you have a complete backup of the N-central server and database before proceeding
- Follow the standard N-central upgrade procedure as documented in the official N-able documentation at documentation.n-able.com
- After upgrade, verify that the syslog configuration access control vulnerability is resolved by testing cross-customer syslog access restrictions
