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
Authenticated privilege escalation in NetScaler Console and NetScaler Agent allows.

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

Authenticated privilege escalation vulnerability in NetScaler Console (formerly NetScaler MAS) and NetScaler Agent allows an authenticated user to gain elevated privileges beyond their intended role, potentially achieving administrative-level access.

MitigationApply vendor-supplied patches when available; in the interim, restrict administrative access to trusted users only, enforce least-privilege principles, and monitor for suspicious privilege escalation behavior.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 NetScaler Agent version
    Run command 'ns_agent -version' or check /opt/netscaler/agent/version file, or inspect the agent's about page in the management console
    Affected if The installed version matches: 13.1-4.43 through 13.1-56.17, 14.1-4.42 through 14.1-38.52, or specifically 13.0-58.30
  2. Identify NetScaler Console version
    Access the console web UI and navigate to Settings > System Information, or run 'ns_mas -version' via CLI if available
    Affected if The installed version is exactly 13.1 or 14.1 (any build)
  3. Review user account roles
    In the management console, navigate to Administration > Users or Access > Users to enumerate all defined users and their assigned roles
    Affected if Any user account has been assigned a higher privilege role than intended, or unexpected admin-level accounts exist that were not created by known administrators
  4. Audit recent privilege escalation indicators
    Review system logs, audit logs, or security event logs for events indicating role changes, privilege escalation attempts, or unexpected administrative actions
    Affected if Logs show role modifications or administrative actions performed by users who should not have elevated privileges

You are affected if either NetScaler Agent version falls within the listed vulnerable ranges or NetScaler Console is version 13.1 or 14.1, and you have untrusted or unexpected user accounts with elevated privileges.

Recommended fix High confidence

NetScaler Agent: 13.1-56.18 or later, 14.1-38.53 or later; NetScaler Console: latest fixed 13.1 or 14.1 release per Citrix support.citrix.com

  1. 1. Identify the current installed version of NetScaler Agent or NetScaler Console using the system management interface or command line
  2. 2. For NetScaler Agent: If running version 13.1-4.43 or later but below 13.1-56.18, plan upgrade to version 13.1-56.18 or later
  3. 3. For NetScaler Agent: If running version 14.1-4.42 or later but below 14.1-38.53, plan upgrade to version 14.1-38.53 or later
  4. 4. For NetScaler Agent: If running exactly version 13.0-58.30, plan upgrade to a supported fixed release (13.1-56.18+ or 14.1-38.53+)
  5. 5. For NetScaler Console: If running version 13.1, upgrade to the latest 13.1 stable release that includes the fix
  6. 6. For NetScaler Console: If running version 14.1, upgrade to the latest 14.1 stable release that includes the fix
  7. 7. Schedule maintenance window and back up current configuration
  8. 8. Apply the upgrade following Citrix upgrade documentation
Caveat Review Citrix upgrade documentation for your specific version path for any migration requirements or compatibility considerations
