1. Introduction
VMware vRealize Operations for Published Applications Desktop Agent is a virtual machine management application installed on Windows hosts, used for collecting metrics and performance data. Its presence indicates systems are monitored by VMware’s vRealize Operations suite. A compromise could allow an attacker to access performance data or potentially escalate privileges within the managed environment. This vulnerability has an informational severity level.
2. Technical Explanation
The vulnerability involves the installation of VMware vRealize Operations for Published Applications Desktop Agent on Windows systems. While not directly exploitable remotely, its presence signals a potential attack surface and requires assessment. There is no known CVE associated with this specific detection. An attacker gaining access to the host could potentially leverage the agent for further reconnaissance or lateral movement within the network. Affected versions are those where the agent is installed.
- Root cause: The application itself isn’t flawed, but its installation represents a potential risk point due to its data collection and management capabilities.
- Exploit mechanism: An attacker with local access could attempt to modify or misuse the agent’s configuration or collected data for malicious purposes.
- Scope: Windows hosts running VMware vRealize Operations for Published Applications Desktop Agent.
3. Detection and Assessment
Confirming the presence of the agent is key to assessing this risk. A quick check can identify installations, while more thorough methods involve reviewing installed programs or using scanning tools.
- Quick checks: Use PowerShell to list installed applications. Look for “VMware vRealize Operations for Published Applications Desktop Agent” in the output.
- Scanning: Nessus plugin ID 168739 can detect VMware vRealize Operations installations, but may not specifically identify this agent. This is an example only.
- Logs and evidence: Review Windows Event Logs for installation events related to VMware vRealize Operations.

The remediation involves assessing the need for the agent and potentially removing it if not required. If needed, ensure the latest version is installed and properly configured.
4.1 Preparation
- Ensure you have administrative privileges to uninstall applications. A roll back plan involves restoring from backup or snapshot.
- A change window may be needed depending on service impact. Approval from the IT management team is recommended.
4.2 Implementation
- Step 1: Open the Control Panel and navigate to Programs and Features.
- Step 2: Locate “VMware vRealize Operations for Published Applications Desktop Agent” in the list of installed programs.
- Step 3: Right-click on the agent and select Uninstall.
- Step 4: Follow the on-screen prompts to complete the uninstallation process.
4.3 Config or Code Example
Before
VMware vRealize Operations for Published Applications Desktop Agent is listed in Programs and Features.After
VMware vRealize Operations for Published Applications Desktop Agent is not listed in Programs and Features.4.4 Security Practices Relevant to This Vulnerability
Practices that address this vulnerability type include least privilege and regular software inventory. Least privilege limits the impact of a compromised agent, while inventory helps identify unnecessary software.
- Practice 1: Implement least privilege principles to restrict access to sensitive data and system resources.
- Practice 2: Maintain an accurate software inventory to identify and remove unused or unnecessary applications.
4.5 Automation (Optional)

Confirming the uninstallation is key to verifying the fix. Re-run the earlier detection method and check for any remaining traces of the agent.
- Post-fix check: Run `Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like “*vRealize Operations*”}`. The output should be empty.
- Re-test: Repeat the quick check from Section 3. No instances of “VMware vRealize Operations for Published Applications Desktop Agent” should be found.
- Smoke test: Verify that any dependent applications or services continue to function as expected.
