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
An Improper Access Control vulnerability exists in Citrix Workspace App for Linux 2012 - 2111 with App Protection installed that can allow an attacker to perform local privilege escalation.

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 Improper Access Control vulnerability in Citrix Workspace App for Linux (versions 2012-2111) when App Protection is installed. The flaw allows a local attacker to perform privilege escalation, likely by exploiting insufficient restrictions on file permissions, processes, or access controls within the protected component.

MitigationUpdate Citrix Workspace App for Linux to a version beyond 2111 once the patch is released, or disable App Protection if operationally feasible as a temporary measure while awaiting the fix.

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 App for Linux is installed
    Run command: dpkg -l | grep -i citrix or rpm -qa | grep -i citrix or which ctxworkspace
    Affected if No Citrix Workspace App for Linux found means not affected by this CVE
  2. Determine installed Citrix Workspace version
    Run command: /opt/Citrix/workspaceapp/version.sh or dpkg -l | grep workspaceapp (version format is YYYYMM like 2012, 2109, 2111)
    Affected if Version falls between 2012 and 2111 inclusive; versions before 2012 or 2112 and later are not affected
  3. Check if App Protection component is installed
    Look for App Protection files/directories: ls -la /opt/Citrix/workspaceapp/AppProtection/ or check for app protection daemon: ps aux | grep -i appprotection
    Affected if App Protection is not installed or not present means the vulnerability cannot be exploited; the flaw only affects systems WITH App Protection enabled
  4. Inspect file permissions on Citrix directories
    Run: ls -la /opt/Citrix/workspaceapp/ and check for world-writable permissions or unusual ownership on configuration files and binaries
    Affected if Find world-writable permissions or files owned by unprivileged users within the Citrix directory structure indicates the access control weakness is present

User is affected if Citrix Workspace App for Linux versions 2012-2111 is installed AND App Protection component is enabled/present on the system.

Fixed in 2112
Interim mitigation

Update Citrix Workspace App for Linux to a version beyond 2111 once the patch is released, or disable App Protection if operationally feasible as a temporary measure while awaiting the fix.

Recommended fix High confidence

Citrix Workspace App for Linux 2112 or later

  1. 1. Back up current Citrix Workspace App configuration files in /opt/Citrix/WorkspaceApp or ~/.ICAClient
  2. 2. Uninstall the current version of Citrix Workspace App for Linux using the package manager (e.g., sudo apt-get remove citrix-workspace or sudo yum remove citrix-workspace)
  3. 3. Download Citrix Workspace App for Linux version 2112 or later from support.citrix.com
  4. 4. Install the new version using the appropriate package manager (e.g., sudo dpkg -i <package.deb> or sudo rpm -i <package.rpm>)
  5. 5. Verify the installed version matches or exceeds 2112 using: cat /opt/Citrix/WorkspaceApp/version.ini or ctxworkspace --version
  6. 6. Restart the Citrix Workspace App service if needed (sudo systemctl restart ctxwise)
  7. 7. If App Protection was previously configured, verify App Protection components are functioning correctly after upgrade
