Cryptographp - a `free` captcha script I contacted the author on 2009-02-11 via e-mail but I did not get a response. I feel the need users of that script should be aware of such a bug. The main include of that script has the following PHP code: ##### if (is_file($_GET['cfg']) and dirname($_GET['cfg'])=='.' ) $_SESSION['configfile']=$_GET['cfg']; else $_SESSION['configfile']="cryptographp.cfg.php"; include($_SESSION['configfile']): ##### This enables an attacker to output any file in the current directory, where cryptographp has been installed. For example you can read .ht* files like .htpasswd, .htaccess Vulnerable: Latest Version 1.4 (did not check below)
