ColdFusion Double-Encoded Null Byte Information Disclosure Vulnerability

Vulnerability Assessment Summary
Tries to retrieve script source code using ColdFusion

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server is affected by an information disclosure
vulnerability.

Description :

The remote host is running Abobe Macromedia ColdFusion, a product for
developing and deploying web applications.

The version of ColdFusion installed on the remote host permits an
attacker to view the contents of files not interpreted by ColdFusion
itself and hosted on the affected system. The problem is due to the
fact that with ColdFusion, URL-encoded filenames are decoded first by
IIS and then again by ColdFusion. By passing in a filename followed
by a double-encoded null byte and an extension handled by ColdFusion,
such as '.cfm', a remote attacker can may be able to uncover sensitive
information, such as credentials and hostnames contained in scripts,
configuration files, etc.
