Hello,

this kind of "vulnerabilities" exists whenever a PHP scripts issue a fatal
error on a poorly configured server. PHP should log errors in a local file
and not on the client screen. With this configuration, you will not see a
full path disclosure in each uncatched PHP exception. IMHO the security
weakness is on the php.ini and not on the web application.

cheers,

majinboo
