Re: AWstats Path Disclosure Vulnerability

Thing is, it's a MINOR bug.  Since most people install it in the default
/cgi-gin and usually under /awstats, it doesn't give much ammo other then
possibly the userid of the account.  And since a LOT of ppl use something
easy like "admin" or a shortened version of teh domain name like
"domai00", it's not hard to guess the paths.   Besides, a lot of ppl also
have a phpinfo.php file on their sites or servers...that gives you much
more information then this does.

This is nothing more then a minor bug then a real security issue.

Hi !

If you use this url :
http://www.server.com/awstats/awstats.pl?config=xxx

You will get the full path on the hard drive of the script "awstats.pl"
with all sub folders.
To prevent an attack, this is the kind of information you should hide.

If you search "full path disclosure" on google or on bugtraq you will
find many security issue.
It is not a critical vulnerability but we should be aware.

Best regards.

Hi!

Once you have setup this tool, you can get statistics of a website
with this URL :

http://www.server.com/awstats/awstats.pl?config=xxx

You replace xxx by the name you gave to the configuration file of
your website (You have one file per website)

But if xxx is not an existing name, the path will be disclosed to
the user in the resulting error message.



I'm afraid I don't understand this properly - You request
http://some.url?config=/path/to/nonexistant and the error page
displays exactly this path? How can this be a vulnerability? AFAICS
this can only determine whether a file exists or not, but this is
really picky...

Thanks for any clarification,

Martin
