|
|
Stefan Esser discovered that mod_security processes NULL characters as
|
|
terminators in POST requests using the
|
|
application/x-www-form-urlencoded encoding type, while other parsers
|
|
used in web applications do not.
|
|
</p>

|
<impact type="low">
|
|
<p>
|
|
A remote attacker could send a specially crafted POST request, possibly
|
|
bypassing the module ruleset and leading to the execution of arbitrary
|
|
code in the scope of the web server with the rights of the user running
|
|
the web server.

|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All mod_security users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-apache/mod_security-2.1.1"</code>
