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
Unspecified vulnerability in the management GUI in Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway before 9.3-66.5 and 10.x before 10.1-122.17 has unspecified impact and vectors, related to certificate validation.

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

A certificate validation vulnerability exists in the management GUI of Citrix NetScaler ADC and NetScaler Gateway. The flaw allows unspecified impact due to improper validation of certificates in the management interface, likely enabling man-in-the-middle attacks or authentication bypass.

MitigationUpgrade Citrix NetScaler to version 9.3-66.5 or later, or 10.1-122.17 or later for the respective version branches.

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 the NetScaler product type
    Run 'show version' or 'nsversion' command on the NetScaler CLI, or check the management GUI login page banner for product name (Access Gateway or Application Delivery Controller)
    Affected if The product is Citrix NetScaler Access Gateway or NetScaler ADC
  2. Determine the firmware version
    Execute 'show version' or 'nsversion' on the CLI, or go to System > Information > Version in the management GUI
    Affected if Version is 9.3 (any build), 10.1 (any build), or any version <= 9.3.e or <= 10.1.e based on the product type
  3. Check if management GUI is enabled
    Run 'show nshttp' or 'show management' on the CLI to verify the management interface (nsGui or SSL) service is enabled, or attempt to access https://<netscaler-ip>/ on a browser
    Affected if The management GUI service is active and reachable on the network
  4. Verify SSL/TLS settings for management interface
    Run 'show ssl service' or check System > SSL Settings in the management GUI to see certificate configuration for the management virtual server
    Affected if A custom or default certificate is bound to the management service (default condition if GUI works)

A user is affected if they run Citrix NetScaler (Access Gateway or ADC) with firmware version 9.3, 10.1, or any version <= 9.3.e or <= 10.1.e and have the management GUI enabled.

dbcve · scoped
Upgrade available Upgrade to a release after 10.1.e
Interim mitigation

Upgrade Citrix NetScaler to version 9.3-66.5 or later, or 10.1-122.17 or later for the respective version branches.

Recommended fix Moderate confidence

9.3-66.5 or later for 9.x branch; 10.1-122.17 or later for 10.x branch

  1. Identify the currently installed NetScaler firmware version via the management GUI or CLI (show version command)
  2. If running version 9.3.x, plan upgrade to firmware version 9.3-66.5 or later
  3. If running version 10.1.x, plan upgrade to firmware version 10.1-122.17 or later
  4. For versions outside these branches (e.g., 10.0, 10.5), contact Citrix support for specific patched firmware
  5. Download the appropriate firmware from Citrix support portal (support.citrix.com)
  6. Review NetScaler upgrade documentation before proceeding
  7. Perform upgrade during a maintenance window as the ADC/Gateway will require a restart
  8. After upgrade, verify the management GUI is accessible and the new version is reported correctly
Caveat Standard NetScaler upgrade procedures apply - expect brief downtime during reboot; ensure configuration backup before upgrading
