###################################################################### # Exploit Title: Java.com RXSS and DOM-XSS # Date: 01/04/2015 # Author: Yann CAM @ Synetis - ASafety # Vendor or Software Link: java.com: Java + You # Version: / # Category: Reflected Cross Site Scripting and DOM based XSS # Google dork: # Tested on: Java.com main domain ###################################################################### Java description : ====================================================================== As of 2015, Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them. Java.com is the main website to acquire Java JRE or JDK software. RXSS Vulnerability description - PoC n°1 : ====================================================================== A reflected XSS is available in the java.com main domain. Through this vulnerability, an attacker could tamper with page rendering, redirect victims to fake Java portals, or capture Java's users credentials such cookies. It's also possible to forge a fake Java's page with this XSS to provide a backdoored version of softwares to users. This reflected XSS is on GET "n" variable and is not properly sanitized before being used to his page. Tested on Firefox 32.0.
