VAMI must have Multipurpose Internet Mail Extensions (MIME) that invoke OS shell programs disabled.

| Description |
|---|
| Controlling what a user of a hosted application can access is part of the security posture of the web server. Any time a user can access more functionality than is needed for the operation of the hosted application poses a security issue. A user with too much access can view information that is not needed for the user's job role, or the user could use the function in an unintentional manner. A MIME tells the web server what type of program various file types and extensions are and what external utilities or programs are needed to execute the file type. There is no reason for VAMI to have MIME types configured for shell scripts. |
