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

Critical Nessus Plugin ID 78826

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 9.6

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.
