Synopsis

The remote host is running a vulnerable version of Bash.

Description

According to its self-reported version, the remote host is running a version of Cisco UCS Director that could be 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.

Authentication on the system is required before this vulnerability can be exploited.
