<title>AWStats: Remote code execution</title>

<synopsis>
|
|
|
|
|
AWStats fails to validate certain input, which could lead to the remote
|
|
|
|
|
execution of arbitrary code or to the leak of information.

|
When 'awstats.pl' is run as a CGI script, it fails to validate specific
|
|
|
|
|
inputs which are used in a Perl open() function call. Furthermore, a
|
|
|
|
|
user could read log file content even when plugin rawlog was not
|
|
|
|
|
enabled.

<p>
|
|
|
|
|
A remote attacker could supply AWStats malicious input, potentially
|
|
|
|
|
allowing the execution of arbitrary code with the rights of the web
|
|
|
|
|
server. He could also access raw log contents.
|
|
|
|
|

</impact>
|
|
|
|
|
<workaround>
|
|
|
|
|
<p>
|
|
|
|
|
Making sure that AWStats does not run as a CGI script will avoid the
|
|
|
|
|
issue, but we recommend that users upgrade to the latest version, which
|
|
|
|
|
fixes these bugs.
|
|
|
|
|
</p>
|
|
|
|
|
</workaround>
|
|
|
|
|
<resolution>
|
|
|
|
|
<p>
|
|
|
|
|
All AWStats users should upgrade to the latest version:
|
|
|
|
|
</p>
|
|
|
|
|
<code>
|
|
|
|
|
# emerge --sync
|
|
|
|
|
# emerge --ask --oneshot --verbose ">=www-misc/awstats-6.3-r2"</code>
|
|
|
|
|
<p>
|
|
|
|
|
Note: Users with the vhosts USE flag set should manually use
|
|
|
|
|
webapp-config to finalize the update.
