Multiple vulnerabilities have been reported in AWStats, which potentially can be exploited by malicious, local users to gain escalated privileges, and by malicious people to disclose system information, cause a DoS (Denial of Service), or compromise a vulnerable system.

1) An error in "awstats.pl" may disclose log file content when the rawlog plugin is disabled.

Example:
http://[victim]/awstats/awstats.pl?pluginmode=rawlog&loadplugin=rawlog

The vulnerability has been reported in versions 6.3 and prior.

2) Input passed to the "loadplugin" and "pluginmode" parameters is not sufficiently sanitised before being used in an "eval()" expression and may be exploited to cause a DoS.

The vulnerability has been reported in versions 6.3 and prior.

3) Input passed to the "loadplugin" parameter in "awstats.pl" is not properly sanitised before being used to include plugins. This can be exploited to include modules from local resources via directory traversal attacks.

The vulnerability has been reported in versions 6.3 and prior.

4) An error in "awstats.pl" may disclose debug information when the "debug" parameter is specified.

Example:
http://[victim]/awstats/awstats.pl?debug=1

The vulnerability has been reported in versions 6.3 and prior.

5) Input passed as a referrer to the "url" parameter is not properly sanitised before being used. This can be exploited to execute arbitrary Perl code with the privileges of the web server.

Successful exploitation requires that at least one URLPlugin is enabled.

The vulnerability has been reported in versions 6.4 and prior. However, iDEFENSE and the vendor disagree whether or not the vulnerability is exploitable in version 6.4.

Solution
All vulnerabilities have been fixed in version 6.5.
