1. Introduction
HPE Moonshot Provisioning Manager Detection indicates a web server is running on a system providing PXE and DHCP services. This could allow an attacker to gain access to sensitive information or compromise the network. Systems affected are those running HPE Moonshot Provisioning Manager. A successful exploit may impact confidentiality, integrity, and availability of the provisioning environment.
2. Technical Explanation
The remote host is running HPE Moonshot Provisioning Manager, which includes a web server accessible over the network. This web server may be exposed without appropriate security measures. An attacker could potentially exploit vulnerabilities in the web server to gain control of the system or access sensitive data. There are no known CVEs associated with this specific detection; it represents an information disclosure risk due to potential misconfiguration.
- Root cause: The HPE Moonshot Provisioning Manager web server is running and accessible, potentially without authentication or other security controls.
- Exploit mechanism: An attacker could attempt to access the web interface of the provisioning manager using a standard web browser. If no authentication is required, they may be able to view sensitive information or modify system settings.
- Scope: HPE Moonshot Provisioning Manager installations are affected.
3. Detection and Assessment
Confirm whether a system is vulnerable by checking if the web server is running and accessible. A quick check can identify its presence, while thorough methods involve port scanning and banner grabbing.
- Quick checks: Use `netstat -tulnp` to see if any processes are listening on ports commonly used by web servers (e.g., 80, 443).
- Scanning: Nessus plugin ID 38773db5 can identify the HPE Moonshot Provisioning Manager web server.
- Logs and evidence: Check system logs for any activity related to the web server process.

Fix the issue by securing or disabling the web server associated with HPE Moonshot Provisioning Manager.
4.1 Preparation
- Ensure you have access credentials for the system in case of rollback. A roll back plan is to restore the previous configuration or restart the service.
- A change window may be required depending on your environment and impact assessment. Approval from IT management might be needed.
4.2 Implementation
- Step 1: Disable the web server if it’s not actively used. This is the most secure option.
- Step 2: If the web server must remain enabled, configure strong authentication (e.g., username/password or certificate-based authentication).
- Step 3: Restrict access to the web server using firewall rules, allowing only authorized IP addresses or networks.
4.3 Config or Code Example
Before
# No authentication configured for the web serverAfter
# Authentication enabled with username/password or certificate-based access control. Consult HPE documentation for specific configuration details.4.4 Security Practices Relevant to This Vulnerability
List only practices that directly address this vulnerability type. Use neutral wording and examples instead of fixed advice. For example: least privilege, input validation, safe defaults, secure headers, patch cadence.
- Practice 1: Least privilege – limit access to the provisioning manager web server to authorized personnel only.
4.5 Automation (Optional)
# Example PowerShell script to check firewall rules for access restrictions:
# Get-NetFirewallRule -DisplayName "Allow HPE Moonshot Provisioning Manager Access" | Select-Object Enabled, Direction, LocalPort, RemoteAddress
5. Verification / Validation
Confirm the fix worked by verifying that authentication is enabled or access is restricted. Provide commands and expected outputs.
- Post-fix check: Attempt to access the web server without credentials. You should be prompted for authentication if configured correctly.
- Re-test: Re-run `netstat -tulnp` and Nessus plugin ID 38773db5 to confirm that the web server is still running but now requires authentication or has restricted access.
- Monitoring: Monitor system logs for failed login attempts or unauthorized access attempts to the web server.
# Attempt to access the web interface via a browser - should prompt for credentials if configured correctly.6. Preventive Measures and Monitoring
Suggest only measures that are relevant to the vulnerability type. Use “for example” to keep advice conditional, not prescriptive.
- Baselines: Update your security baseline or policy to include requirements for strong authentication and access control on all web servers.
- Asset and patch process: Implement a regular asset inventory and vulnerability scanning process to identify systems running HPE Moonshot Provisioning Manager and assess their security configuration.
7. Risks, Side Effects, and Roll Back
- Risk or side effect 1: Disabling the web server may disrupt access for users who rely on it.
- Risk or side effect 2: Incorrect firewall configuration could block legitimate access.
- Roll back: If disabling the web server causes issues, re-enable it using the original configuration. If authentication fails, revert to the previous settings.
