RE: Possible iSeries HTTP vulnerabilties TRACE and/or TRACK methods

V6R1 info center shows default is on.
V7R1 info center show default is off.
Did the default change from V6R1 to V7R1, or could there be a typo in the
center.

With Windows7 , can't use the recommended TELNET test to confirm the
status.

"Normally you will have this enabled by default, but if you want to test
if it is really enabled on your server you just have to telnet on the port
your web server is running and request for "TRACE / HTTP/1.0" if you get a
positive reply it means TRACE is enabled on your system.

Any recommendations on how to confirm.

So even if TraceEnable is not in the httpconf file, by default it is off.

According to the InfoCenter directive reference, if not specified the
default is

TraceEnable off

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 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.
