Subject: Possible iSeries HTTP vulnerabilties TRACE and/or TRACK
methods
Sent by: midrange-l-bounces@xxxxxxxxxxxx
Security audit is requesting that these vulnerabilities be disabled.
Reviewing the httpd.conf config files, I see no evidence of TRACE and/or
TRACK, so I'm assuming these are on by default, and need to be disabled by
one of the suggested methods.
All of our HTTP instances are Apache 2.2.11(i5).
Am I correct that I need to re-visit every HTTP instance, adding one of
the two recommendations below.
To disable
TraceEnabled Off
OR
...
# disable TRACE in the main scope of httpd.conf
RewriteEngine On
RewriteCond %{REQUEST_METHOD} ^TRACE
RewriteRule .* - [F]
...
<VirtualHost www.example.com>
...
# disable TRACE in the www.example.com virtual host
RewriteEngine On
RewriteCond %{REQUEST_METHOD} ^TRACE
RewriteRule .* - [F]
</VirtualHost>
mod_rewrite must be active for these directives to be accepted. If
mod_rewrite is not already active in your configuration:
Plugin Text: Synopsis: Debugging functions are enabled on the remote web
server.
Description: The remote web server supports the TRACE and/or TRACK
methods. TRACE and TRACK are HTTP methods that are used to debug web
server connections.
Solution: Disable these methods. Refer to the plugin output for more
information.

Risk Factor: Medium
CVSS Base Score: 4.3
CVSS Vector: CVSS2#AV:N/AC:M/Au:N/C:P/I:N/A:N
CVSS Temporal Score: 3.9
CVSS Temporal Vector: CVSS2#E:F/RL:W/RC:C
Plugin Output:
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.
