F5 Networks BIG-IP : BIG-IP Azure cloud vulnerability (K61757346)

critical Nessus Plugin ID 100331

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

In some circumstances, a BIG-IP Azure cloud instance may contain a default administrative password which can be used to remotely log in to the BIG-IP system.

The affected administrative account is the Azure instance administrative user created at deployment. The root and admin accounts are not vulnerable.

This issue only affects BIG-IP Virtual Edition (VE) Azure instances and Azure Web Application Firewall solutions on the Azure Marketplace.
This issue does not affect BIG-IP VE instances on any other cloud services. All BIG-IP VE Azure instances licensed for any product are affected by this vulnerability, except :

Instances deployed using solution templates.

Instances deployed using a password rather than public key for the user-defined account during provisioning.

Note : For more information about deploying instances using solution templates, refer to the DevCentral Deploy BIG-IP VE in Microsoft Azure Using an ARM Template article. A DevCentral login is required to access this content.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K61757346.
