The awstats.pl script that ships with the WRE will reveal configuration information about the server which could potentially be used to obtain server information by a hacker. Here's an example of the output:
Error: Couldn't open config file "awstats.www.nodomain.com.conf" nor "awstats.conf" after searching in path "/data/wre/prereqs/wwwroot,/data/wre/etc,/etc/awstats,/usr/local/etc/awstats,/etc,/etc/opt/awstats": No such file or directory
I didn't see a way to hide this via awstats configuration options so think it should be a customization of the script included in the WRE distribution. This appears to be the default behavior of awstats as can be seen by hacking the config option for the demo site -- http://www.nltechno.com/awstats/awstats.pl?config=HACKdestailleur.fr.
