Privilege Escalation Risk in VMware Aria Operations and VMware Tools

Historical catalog analysis: CISA added this entry on October 30, 2025. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2025-41244 is a privilege escalation vulnerability (CWE-267) involving “privilege defined with unsafe actions” within Broadcom VMware Aria Operations and VMware Tools. This flaw allows a local actor who already possesses non-administrative privileges on a virtual machine (VM) to escalate those permissions to root level on that same VM.

Exposure and applicability

This vulnerability is not a remote entry point; it requires the attacker to already have local access to the system. For healthcare organizations, the risk is specific to environments meeting three concurrent conditions:
1. The VM has VMware Tools installed.
2. The VM is managed by VMware Aria Operations.
3. The Service Delivery Management Platform (SDMP) feature is enabled.

In a clinical data center context, if these conditions are met on servers hosting electronic Protected Health Information (ePHI) or critical medical applications, a compromised low-privilege account could be used to gain full administrative control over the guest operating system, potentially bypassing internal access controls designed to protect patient data.

Remediation priorities

Our analysis suggests that healthcare IT and security teams prioritize remediation based on the sensitivity of the workloads hosted on the affected VMs. We recommend the following prioritized actions:

1. Identify High-Risk Assets: Audit virtualized environments to identify VMs that host ePHI or critical clinical systems and verify if they are managed by Aria Operations with SDMP enabled. (Responsible: Virtualization Administrator)
2. Apply Vendor Mitigations: Implement the mitigations provided by Broadcom for VMware Aria Operations and VMware Tools to address the unsafe action definitions. (Responsible: Systems Administrator)
3. Review Local Access Controls: Since this is a local escalation flaw, evaluate the current state of non-administrative accounts on critical VMs to reduce the number of potential local actors who could attempt exploitation. (Responsible: Security Analyst)

How to validate remediation

To verify that exposure has been reduced, administrators should:
* Verify Versioning/Patch Status: Confirm that the specific mitigations or updates recommended by Broadcom have been successfully applied across all identified VMs.
* Configuration Audit: Verify whether SDMP is required for business operations; if it is not necessary for a specific clinical workload, disabling the feature would remove the prerequisite for this vulnerability.

Note: A version check alone does not guarantee total security against all privilege escalation vectors, but it confirms the specific flaw identified in CVE-2025-41244 has been addressed.

Limits and open questions

It remains unknown whether this vulnerability has been utilized in active ransomware campaigns. Furthermore, while applying vendor mitigations reduces the likelihood of this specific escalation path, it does not eliminate the risk of other local privilege escalation vulnerabilities that may exist within the guest operating system or other installed software. Organizations should continue to follow a defense-in-depth strategy, as no single patch guarantees total prevention of all unauthorized access attempts.
