CVE-2023-24486: Local user access to a system where another user is utilizing a vulnerable version of Citrix Workspace App for Linux to launch published desktops and applications

A vulnerability has been identified in Citrix Workspace app for Linux that, if exploited, may result in a malicious local user being able to gain access to the Citrix Virtual Apps and Desktops session of another user who is using the same computer from which the ICA session is launched.

Security readout for executives and security teams

Plain-English summary

This affects Citrix Workspace app for Linux on shared computers. A local malicious user could access another user's Citrix Virtual Apps and Desktops session launched from the same machine. The business risk is unauthorized viewing of remote applications or desktop data, not system-wide remote takeover.

Executive priority

Treat as a targeted confidentiality risk for shared Linux endpoints using Citrix. It is not currently evidenced as internet-exploited, but shared workstations handling sensitive remote apps should be prioritized.

Technical view

CVE-2023-24486 is an improper access control issue in Citrix Workspace app for Linux. CVSS 3.1 is 5.5: local attack vector, low complexity, low privileges, no user interaction, unchanged scope, high confidentiality impact, and no integrity or availability impact.

Likely exposure

Exposure is most likely on Linux endpoints where Citrix Workspace app is installed and multiple local users can access the same computer. Single-user managed endpoints have lower practical exposure based on the local-user prerequisite.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. Exploitation requires local user access to a system where another user launches Citrix Virtual Apps and Desktops through a vulnerable Linux Workspace app.

Researcher notes

The affected-version detail in the provided bundle is incomplete, so version scoping should come from Citrix CTX477618. The vulnerability maps to CWE-284 and is bounded by local access plus another active Citrix session on the same computer.

Mitigation direction

  • Review Citrix bulletin CTX477618 for affected and fixed Workspace app for Linux versions.
  • Update vulnerable Citrix Workspace app for Linux installations according to vendor guidance.
  • Limit local account access on shared Linux endpoints running Citrix Workspace app.
  • Prioritize shared kiosks, labs, jump boxes, and contractor workstations for remediation.

Validation and detection

  • Inventory Linux endpoints with Citrix Workspace app installed.
  • Compare installed versions against Citrix bulletin CTX477618.
  • Identify systems where multiple local users can log in or access the same host.
  • Confirm remediation by documenting updated versions or vendor-approved mitigations.
