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.

Arbitrary file read in NetScaler Console and NetScaler SDX (SVM)

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

This is an arbitrary file read vulnerability in NetScaler Console and NetScaler SDX (SVM) that allows authenticated attackers to read arbitrary files from the underlying filesystem, potentially exposing sensitive configuration files, credentials, or other system data.

MitigationApply the vendor patch or upgrade to a patched version of NetScaler Console or NetScaler SDX. If patching is not immediately possible, restrict network access to the management interfaces and ensure strong authentication is enforced.

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 the NetScaler product and version
    Log into the NetScaler command-line interface and run 'show version' or 'nsversion' to display the installed build version. For SDX appliances, you may also need to check the SVM version using 'show sdx version' or similar SVM-specific command.
    Affected if The displayed version matches one of the affected ranges: for Console = 13.1 or = 14.1; for SDX 13.1-49.13 through 13.1-58.32, or 14.1-4.42 through 14.1-47.46.
  2. Confirm the product type is affected
    Determine whether the system is NetScaler Console (formerly Citrix ADM) or NetScaler SDX. The CVE affects both products but with different version schemes. Check the product name in the management interface or banner.
    Affected if The product is Citrix NetScaler Console version 13.1 or 14.1, or Citrix NetScaler SDX with a version in the affected ranges listed above.
  3. Verify if management interface is network-accessible
    Check network accessibility of the management interface (typically ports 443 or 80) from untrusted networks. This can be done by attempting to reach the management IP from an external location or reviewing firewall rules that permit access to management ports.
    Affected if The management interface is reachable from networks that are not explicitly trusted, increasing the attack surface for this authenticated vulnerability.
  4. Check authentication configuration
    Review the authentication settings for the management interface to confirm whether local or external authentication (such as LDAP or RADIUS) is properly configured and enforced.
    Affected if Authentication is not enforced, weak credentials exist, or the default admin account is still in use with default credentials - since this vulnerability requires an authenticated attacker.

You are affected if you are running NetScaler Console 13.1 or 14.1, or NetScaler SDX with a version between 13.1-49.13 and 13.1-58.32 or between 14.1-4.42 and 14.1-47.46, and the management interface is accessible to an attacker who could obtain valid credentials.

Upgrade available Upgrade to 13.1-58.32 / 14.1-47.46 or later
Fixed in 13.1-58.3214.1-47.46
Interim mitigation

Apply the vendor patch or upgrade to a patched version of NetScaler Console or NetScaler SDX. If patching is not immediately possible, restrict network access to the management interfaces and ensure strong authentication is enforced.

Recommended fix Moderate confidence

NetScaler SDX: 13.1-58.32 or later, 14.1-47.46 or later; NetScaler Console: 13.1-58.32 or later, 14.1-47.46 or later

  1. 1. Identify the currently installed NetScaler Console or SDX version by navigating to the system administration or diagnostics section.
  2. 2. For NetScaler SDX 13.1: Plan upgrade to version 13.1-58.32 or later.
  3. 3. For NetScaler SDX 14.1: Plan upgrade to version 14.1-47.46 or later.
  4. 4. For NetScaler Console 13.1: Upgrade to version 13.1-58.32 or later.
  5. 5. For NetScaler Console 14.1: Upgrade to version 14.1-47.46 or later.
  6. 6. Back up current configuration before performing the upgrade.
  7. 7. Download the appropriate fixed build from support.citrix.com.
  8. 8. Apply the upgrade following Citrix standard upgrade procedures for the respective platform.
