CVE-2002-0253

PHP, when not configured with the "display_errors = Off" setting in php.ini, allows remote attackers to obtain the physical path for an include file via a trailing slash in a request to a directly accessible PHP program, which modifies the base path, causes the include directive to fail, and produces an error message that contains the path.
