Hello, That definitely can be fixed easily with two lines of code but is still something that should have been prevented at earlier stages of "plugin" development "if (!empty($_SERVER['SCRIPT_FILENAME']) && 'akismet.php' == basename($_SERVER['SCRIPT_FILENAME'])) die ('Please do not load this page directly');"
From the server side you can set PHP "warning" and "errors" OFF either
through php.ini or PHP page itself but sometimes that's not an option Regards, Glafkos Charalambous From: full-disclosure-bounces () lists grok org uk [mailto:full-disclosure-bounces () lists grok org uk] On Behalf Of majinboo Sent: Monday, September 28, 2009 11:12 PM To: Fernando A. Lagos B. Cc: full-disclosure () lists grok org uk Subject: Re: [Full-disclosure] Full Path Disclosure in most wordpress' plugins [?] 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 2009/9/28 Fernando A.
