Uncredentialed scan error scanning standalone esxi host 7u3 vmware

Products

• VMware vSphere ESXi

Issue/Introduction

After patching standalone esxi host to version 7u3, cx is receiving error: uncredentialed scan error scanning standalone esxi host 7u3 vmware

Cause

Credential type in the scanner's configuration is set to "vCenter" for standalone ESXi host. Credential type in the scanner's configuration should be set to "VMware ESX SOAP API" for standalone ESXi.

Resolution

Scanning vCenter-Managed ESXi/vSpheres

Note: The SOAP API requires a vCenter admin account with read and write permissions. The REST API requires a vCenter admin account with read permissions, and a VMware vSphere Lifecycle manager account with read permissions.

To configure an ESXi/vSphere scan managed by vCenter:

1. Begin configuring a scan policy that supports credentialed access, as described in Add a Scan Policy. For more information about authentication options in scan policies, see The Authentication tab specifies authentication options during a scan..

2. In the left navigation menu, click Authentication.

   The Authentication tab appears.

3. Click Add Authentication Settings.

   The authentication options appear.

4. In the first Type drop-down box, select Miscellaneous.

5. In the second Type drop-down box, select VMware vCenter SOAP API.

6. Click Select.

   The VMware vCenter SOAP API options appear. For more information, see VMware vCenter SOAP API.

7. In the vCenter Host box, type the IP address of the vCenter host.

8. In the vCenter Port box, type the port for the vCenter host.

9. In the Username box, type the username associated with the local vCenter account.

10. In the Password box, type the password associated with the local vCenter account.

11. If the vCenter host is not SSL enabled, disable the HTTPS toggle.

12. If your vCenter host includes an SSL certificate (not a self-signed certificate), enable the Verify SSL Certificate toggle.

13. Click the  button.

    Tenable Security Center applies the VMware vCenter SOAP API authentication options to the scan policy.

    Note: When scanning vCenter-managed ESXis with API credentials, the Nessus Scan information plugin always shows Credentialed Checks: No in the vCenter scan results. To verify that the authentication was successful, check to see that the Nessus Scan Information plugin shows Credentialed Checks: Yes in the scan results of the ESXis.
