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.
