The remote security device is missing a vendor-supplied security patch.Description
The remote ASA Next-Generation Firewall (NGFW) host is missing a security patch. It is, therefore, 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
