I just got this off a Lingo programming list (Macromedia Director 7  
scripting). Thought the Bugtraq community might appreciate it.

Subject: <lingo-l> Shockwave 7 Security Hole  
Dear all,  
Thought this little extract from Macuser might amuse you all (especially in  
the context of recent discussions about viewing users hard  
disks/fileIo/Xtras etc.):  
Macromedia Will Plug Shockwave 7 Security Hole This Week  
10 March - MacUser -- Macromedia is set to close a security loophole in  
Shockwave 7 after MacUser discovered the Web plug-in was sending personal  
user information, including passwords, back to Macromedia.  
The updated plug-in is being tested and will be available this week.  
The problem occurs in Shockwave 7's optional auto-update feature, which  
periodically checks the Macromedia download site for the latest revision of  
If it needs an update, the software reports back to Macromedia the Shockwave  
sites users have visited.  
But in cases where Web sites use password validation in their addresses,  
this information - which can include the passwords, as well as data about  
secure Web sites, even those behind a firewall, and hard disk information -  
is passed back to Macromedia.  
Although security risks are minor because Shockwave 7 encrypts data before  
sending it to Macromedia, other users could get information about how to  
attack a company's network.  
Macromedia was not aware of the problem when contacted, but is creating an  
updated Shockwave 7 plug-in which will strip obvious password information  
and port numbers from URLs before sending them.  
The update will record any non-standard URLs as "Not an http:// server",  
preventing information about local hard disks and ftp sites being  
Macromedia will also add a special parameter to the "embed" tag used to  
place Shockwave movies in a page that will stop the URL being recorded.  
Tut tut.
