MajorSecurity Advisory #32]phpComasy CMS - Multiple Cross Site Scripting Issues Details ======= Product: phpComasy CMS Affected Version: <= 0.7.9 pre Security-Risk: moderated Remote-Exploit: yes Vendor-URL: http://www.phpcomasy.org Vendor-Status: informed Advisory-Status: published Credits ============ Discovered by: David Vieira-Kurz http://www.majorsecurity.de Original Advisory: ============ http://www.majorsecurity.de/index_2.php?major_rls=major_rls32 Introduction ============ phpComasy CMS is a Content Management System. More Details ============ Cross Site Scripting: Input passed directly to the "username" and "password" parameter in "index.php" is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. Fix === Version 0.8 Solution ============= Edit the source code to ensure that input is properly sanitised. You should work with "htmlspecialchars()" or "htmlentities()" php-function to ensure that html tags are not going to be executed. Further it is recommend to set off the "register globals" option in the "php.ini" on your webserver. Example: $pass = htmlentities($_POST['pass']); $test = htmlspecialchars($_GET('test')); ?> History/Timeline ================ 02.11.2006 discovery of the vulnerabilities 02.11.2006 additional tests with other versions 03.11.2006 contacted the vendor 04.11.2006 the vendor contacted me(response) 04.11.2006 vendor confirmed the bugs 05.11.2006 bugs have been fixed 06.11.2006 advisory is written 06.11.2006 advisory released MajorSecurity ======= MajorSecurity is a German penetration testing and security research project which consists of only one person at the present time.
