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
Denial of Service in NetScaler Console (formerly NetScaler ADM), NetScaler Agent, and NetScaler SDX

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 · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-08-01.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

Fixed in 13.0-92.3113.1-53.1713.1-53.22
Recommended fix High confidence

Upgrade to NetScaler Console/Agent: 13.0-92.31, 13.1-53.22, or 14.1-25.53; NetScaler SDX: 13.0-92.31, 13.1-53.17, or 14.1-25.53

  1. 1. Identify the currently installed NetScaler Console, Agent, or SDX version by checking the administration console or running 'show version' CLI command
  2. 2. Determine which product (Console, Agent, or SDX) and which release train (13.0, 13.1, or 14.1) is affected
  3. 3. Review the Citrix NetScaler release notes for the target fixed version to understand any prerequisites or migration considerations
  4. 4. Schedule a maintenance window for the upgrade (DoS vulnerabilities may warrant expedited remediation)
  5. 5. Back up the current configuration before upgrading
  6. 6. Download the appropriate fixed build from support.citrix.com: 13.0-92.31, 13.1-53.22 (or 13.1-53.17 for SDX), or 14.1-25.53
  7. 7. Apply the upgrade following Citrix's standard upgrade procedure for the specific product (Console, Agent, or SDX)
  8. 8. After upgrade, verify the new version is running and the service is operational
Caveat Review Citrix release notes for each target version as minor version upgrades typically retain configuration but may have behavioral changes; test in non-production environment first
