Description

The Citrix Access Gateway provides support for multiple authentication types.
When utilizing the external legacy NTLM authentication module known as
ntlm_authenticator the Access Gateway spawns the Samba 'samedit' command
line utility to verify a user's identity and password. By embedding shell
metacharacters in the web authentication form it is possible to execute
arbitrary commands on the Access Gateway.
