A full path disclosure flaw was found in the way DokuWiki, a standards compliant, simple to use Wiki, performed sanitization of HTTP POST 'prefix' input value prior passing it to underlying PHP substr() routine, when the PHP error level has been enabled on the particular server. A remote attacker could use this flaw to obtain full path location of particular requested DokuWiki page by issuing a specially-crafted HTTP POST request.
