VMware NSX Bash Environment Variable Command Injection (VMSA-2014-0010) (Shellshock)

critical Nessus Plugin ID 78826
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote host is affected by a command injection vulnerability.

Description

The version of VMware NSX installed on the remote host is 4.x prior to 4.0.5 / 4.1.4 / 4.2.1 or 6.x prior to 6.0.7 / 6.1.1. It is, therefore, affected by a command injection vulnerability in GNU Bash known as Shellshock, which is due to the processing of trailing strings after function definitions in the values of environment variables. This allows a remote attacker to execute arbitrary code via environment variable manipulation depending on the configuration of the system.

Solution

Upgrade to VMware NSX version 4.0.5 / 4.1.4 / 4.2.1 / 6.0.7 / 6.1.1 or later.
