Local Privilege escalation allows a low-privileged user to gain SYSTEM privileges in Citrix Workspace app for Windows

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

CVE-2025-4879 is a local privilege escalation vulnerability in Citrix Workspace app for Windows that allows an authenticated low-privileged user to elevate their privileges to SYSTEM level. The vulnerability stems from improper privilege management within the application, enabling a local attacker to escalate beyond their assigned user context.

MitigationApply the vendor-supplied patch for Citrix Workspace app when available. In the interim, limit local user permissions and monitor for suspicious processes spawning from the Citrix Workspace service.

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. Verify Citrix Workspace is installed
    Check the installed programs list via Control Panel > Programs and Features, or run: Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like '*Citrix*Workspace*'}
    Affected if Citrix Workspace app for Windows is present on the system
  2. Determine the installed version number
    Run: Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like '*Citrix*Workspace*'} | Select-Object Name, Version. Alternatively, check the Windows Registry at HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{ProductID} for the DisplayVersion value.
    Affected if The displayed version number is less than 2409 (for example, 2402, 2408, 2312, etc.)
  3. Confirm the Citrix Workspace service exists
    Open Services (services.msc) and look for services named 'Citrix Workspace' or 'Citrix HDX 3D Pro', or run: Get-Service | Where-Object {$_.DisplayName -like '*Citrix*'}
    Affected if A Citrix Workspace service is present and running on the system
  4. Check if low-privileged user context can interact with Citrix service
    Using the system, verify you are running as a standard (non-admin) user. Run: whoami /groups | findstr -i "BUILTIN\\Users". Confirm the Citrix service runs under a higher-privileged account (viewable in Service Properties > Log On tab).
    Affected if The system has a standard user account AND the Citrix Workspace service runs under SYSTEM or Administrator account
  5. Verify the vulnerable privilege assignment exists
    Inspect Citrix Workspace installation directory (typically C:\Program Files\Citrix\Citrix Workspace\) for any scheduled tasks or configurations that grant elevated privileges to user-accessible binaries. Run: Get-Acl -Path "C:\Program Files\Citrix\Citrix Workspace\*" | Select-Object Owner
    Affected if Non-admin users have write or execute permissions to Citrix binaries that run with elevated privileges

A system is affected if Citrix Workspace app for Windows version 2408 or earlier (less than 2409) is installed AND a low-privileged local user account exists on the machine.

Interim mitigation

Apply the vendor-supplied patch for Citrix Workspace app when available. In the interim, limit local user permissions and monitor for suspicious processes spawning from the Citrix Workspace service.

Recommended fix Moderate confidence

2409 or later (Citrix Workspace for Windows)

  1. Identify the currently installed Citrix Workspace version from Add/Remove Programs or the app's About section
  2. Download the latest Citrix Workspace version from official Citrix sources (citrix.com/downloads)
  3. Close all running Citrix Workspace processes via Task Manager
  4. Run the Workspace installer with administrator privileges
  5. Follow the on-screen installation prompts, selecting 'Repair' or 'Upgrade' option
  6. Restart the system after installation completes
  7. Verify the new version is installed and the application launches correctly
Caveat Upgrading may reset some user preferences; ensure configuration backups if applicable
