CVE-2024-6150 Overview
A non-admin user can cause short-term disruption in Target VM availability in Citrix Provisioning. This vulnerability stems from improper authorization (CWE-863), allowing users with limited privileges to impact virtual machine availability within the Citrix Provisioning environment.
Critical Impact
Non-administrative users can disrupt Target VM availability, potentially affecting business operations relying on Citrix Provisioning infrastructure.
Affected Products
- Citrix Provisioning versions prior to current release (non-LTSR)
- Citrix Provisioning 1912 LTSR (CU1 through CU8)
- Citrix Provisioning 2203 LTSR (CU1 through CU4)

Technical Details for CVE-2024-6150
Vulnerability Analysis
This vulnerability is classified as Improper Authorization (CWE-863), indicating that Citrix Provisioning fails to properly enforce authorization checks for certain operations. A local attacker with low-privilege access can exploit this weakness to cause disruption to Target VM availability. The attack requires local access to the system but does not require user interaction, making it exploitable by any authenticated non-admin user within the environment.
The vulnerability affects the confidentiality, integrity, and availability of the local system, though the impact to each is limited in scope. Importantly, there is no impact to downstream systems beyond the initially targeted component.
Root Cause
The root cause lies in improper authorization controls within Citrix Provisioning. The software does not adequately verify that users have sufficient privileges before allowing operations that can affect Target VM availability. This authorization gap allows non-administrative users to perform actions that should be restricted to privileged accounts only.
Attack Vector
The attack vector is local, meaning an attacker must have authenticated access to the Citrix Provisioning environment. The exploitation path involves:
- A non-admin user authenticates to the Citrix Provisioning system
- The user initiates operations that affect Target VM resources
- Due to missing or inadequate authorization checks, the operations succeed
- Target VMs experience short-term availability disruption
This vulnerability does not require any special conditions or user interaction beyond the initial local access, making it relatively straightforward to exploit once an attacker has low-privilege access.
Detection Methods for CVE-2024-6150
Indicators of Compromise
- Unexpected Target VM availability disruptions initiated by non-admin user accounts
- Unusual access patterns from low-privilege users attempting administrative operations
- Log entries showing non-admin users performing VM management operations
- Repeated short-term service disruptions correlated with specific user activity
Detection Strategies
- Monitor Citrix Provisioning logs for operations performed by non-administrative accounts
- Implement alerting for Target VM availability changes initiated by users without admin privileges
- Review access control configurations to identify overly permissive settings
- Correlate authentication events with VM management operations
Monitoring Recommendations
- Enable comprehensive logging within Citrix Provisioning Console
- Configure SIEM rules to detect authorization violations in Citrix infrastructure
- Implement user behavior analytics to identify anomalous activity patterns
- Regularly audit user permissions and role assignments in the Citrix environment
How to Mitigate CVE-2024-6150
Immediate Actions Required
- Review and update Citrix Provisioning to the latest patched version
- Audit user accounts and remove unnecessary access privileges
- Implement strict role-based access control for Citrix Provisioning operations
- Monitor for suspicious activity from non-admin accounts
Patch Information
Citrix has released security updates to address this vulnerability. Organizations running affected versions should apply the appropriate patches immediately. Refer to the Citrix Support Article CTX678025 for detailed patch information and download links for your specific version:
- For Citrix Provisioning 1912 LTSR: Apply the latest cumulative update beyond CU8
- For Citrix Provisioning 2203 LTSR: Apply the latest cumulative update beyond CU4
- For non-LTSR versions: Update to the latest current release
Workarounds
- Restrict local access to Citrix Provisioning servers to only essential personnel
- Implement additional network segmentation to limit exposure of Provisioning servers
- Review and enforce least-privilege principles for all user accounts
- Consider implementing additional monitoring controls until patches can be applied
# Example: Review user privileges in Citrix Provisioning
# Audit current user access levels and document non-admin users
# Remove unnecessary access for users who don't require Provisioning access
# Consult Citrix documentation for proper RBAC configuration
