<title>AWStats: Arbitrary code execution using malicious Referrer information</title>
|
|

AWStats is an advanced log file analyzer and statistics generator.
|
|
In HTTP reports it parses Referrer information in order to display the
|
|
most common Referrer values that caused users to visit the website.
|
|

|
|
<p>
|
|
When using a URLPlugin, AWStats fails to sanitize Referrer URL
|
|
data before using them in a Perl eval() routine.
|
|
</p>
|
|
</description>
|
|
<impact type="high">
|
|
<p>
|
|
A remote attacker can include arbitrary Referrer information in a
|
|
HTTP request to a web server, therefore injecting tainted data in the
|
|
log files. When AWStats is run on this log file, this can result in the
|
|
execution of arbitrary Perl code with the rights of the user running
|
|
AWStats.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Disable all URLPlugins in the AWStats configuration.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All AWStats users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-misc/awstats-6.5"</code>
|
|
<p>
|
|
Note: Users with the vhosts USE flag set should manually use
|
|
webapp-config to finalize the update.
