Vulnerabilities > CVE-2003-1567 - Information Exposure vulnerability in Microsoft Internet Information Services 5.0

#
# This script was written by Thomas Reinke <[email protected]>
# Improvements re TRACK and RFP reference courtesy of <[email protected]>
# Improvements by rd - http_get() to get full HTTP/1.1 support,
# security_warning() instead of security_hole(), slight re-phrasing
# of the description
#
# See the Nessus Scripts License for details
#

# Changes by Tenable:
#   - added solution in the plugin output for JSAS9 (3/29/13)
#   - added CVE xref.
#   - title update (9/18/09)
#   - updated CVSS score (12/14/2015)
#   - Added note when TRACE/TRACK is enabled but reply is empty, added CVSSv3 score. (26/11/2018)

To disable these methods, add the following lines for each virtual
host in your configuration file :

    RewriteEngine on
    RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK)
    RewriteRule .* - [F]

Alternatively, note that Apache versions 1.3.34, 2.0.55, and 2.2
support disabling the TRACE method natively via the 'TraceEnable'
directive.

To disable this method, add the following to the default object

     AuthTrans fn="set-variable"

     set-headers="content-length: -1"
     error="501"

If you are using Sun ONE Web Server releases 6.0 SP2 or below, compile
the NSAPI plugin located at :

http://sunsolve.sun.com/pub-cgi/retrieve.pl?doc=fsalert%2F50603
