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.

Cross SiteScripting vulnerability in Citrix Session Recording allows attacker to perform Cross Site Scripting

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.

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. Confirm Citrix Session Recording component is installed
    Check installed programs or services for 'Citrix Session Recording' on the Delivery Controller or Session Recording server. Look in Windows Add/Remove Programs or check the Session Recording service status.
    Affected if Session Recording component is present on the system
  2. Identify Citrix Virtual Apps and Desktops version
    Open Citrix Studio or navigate to the Delivery Controller, then go to Configuration > Licensing to view the installed version. Alternatively, check the installed programs list for 'Citrix Virtual Apps and Desktops' version number.
    Affected if Version is 1912, 2203, or any version 2311 or lower (any version <= 2311)
  3. Verify Session Recording web interface is enabled
    Check if the Session Recording Player web component or Session Recording Administrator web console is enabled. Inspect IIS or the Session Recording service configuration to confirm the web interface is accessible.
    Affected if Session Recording web interface is enabled and accessible to users

A system is affected if it has Citrix Session Recording installed with Citrix Virtual Apps and Desktops version 1912, 2203, or any version up to and including 2311, and the web interface is enabled.

Upgrade available Upgrade to a release after 2311
Interim mitigation

Apply vendor-supplied patches or updates for Citrix Session Recording; implement input validation and output encoding on user-supplied data.

Recommended fix Moderate confidence

For Current Release: upgrade to 2402 or later; For LTSR: install latest 1912 Cumulative Update

  1. 1. Identify the exact Citrix Virtual Apps and Desktops deployment version in your environment (check both Delivery Controller and Session Recording Server components)
  2. 2. For Current Release (CR) deployments: Upgrade to a release version newer than 2311 that includes the security fix for CVE-2023-6184
  3. 3. For Long Term Service Release (LTSR) deployments running version 1912: Install the latest Cumulative Update (CU) for the 1912 LTSR that addresses this vulnerability
  4. 4. Verify the upgrade by checking the Session Recording component version and confirming the XSS vulnerability is remediated
  5. 5. Test the Session Recording functionality in a non-production environment before deploying to production
  6. 6. After upgrade, clear browser caches and test that the Session Recording player works correctly
