Synopsis :

The remote web server is affected by an information disclosure

Description :

Microsoft IIS 4.0 and 5.0 can be made to disclose fragments of source
code which should otherwise be inaccessible. This is done by appending
'+.htr' to a request for a known '.asp' (or '.asa', '.ini', 'etc')

Solution :

.htr script mappings should be removed if not required.

- open Internet Services Manager
- right click on the web server and select properties
- select WWW service | Edit | Home Directory | Configuration

If .htr functionality is required, install the relevant patches
from Microsoft (MS01-004).
