COMMAND osCommerce multiple XSS vulnerabilities SYSTEMS AFFECTED osCommerce milestones upto 2.2ms1 PROBLEM Daniel Alcántara de la Hoz, Director de Proyectos [daniel.alcantara@iproyectos.com], iProyectos Desarrollos Tecnológicos advisory : http://www.iproyectos.com/english.php --snip-- osCommerce is a widely installed open source shopping e-commerce solution. Some XSS (cross-site scripting) problems exists in versions of osCommerce prior to 3/14/2003 that allow an attacker to inject arbitrary HTML code into a web page. An attacker could guide the victim to a specially crafted url that, when followed, would send the cookie to the attacker. With the cookie of an user, an attacker would be able to hijack his account. iProyectos wont provide direct exploit this time due to the simplicity of the bug (exploitation is straightforward with XSS bugs). Here is a proof of concept on one of the four existent bugs. http://vulnerable.host/default.php?error_message=%3Cscript%20language=javascript%3Ewindow.alert%28document.cookie%29;%3C/script%3E The full list of vulnerabilities is available in our website http://www.iproyectos.com/english.php that explains the four bugs. --snap-- SOLUTION To patch, update by CVS. Downloading the last milestone WON'T fix this.
