Juniper Junos Space GNU Bash Command Injection Vulnerability (JSA10648) (Shellshock)

Critical Nessus Plugin ID 80196

Synopsis

The remote device is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the remote Junos Space version is prior to 14.1R2, and may be affected by a command injection vulnerability in GNU Bash known as Shellshock. The vulnerability 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 Junos Space 14.1R2 or later or apply the relevant patch referenced in the vendor advisory.
