Citrix Access Gateway Command Execution
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.
