12	12	LIferay includes numerous portlets. The "XSL Content" portlet displays the result of the XSL transformation of a XML document. The XSLT engine used by default is [[Xalan-J>>Engine_Saxon]] (but this can probably modified easily using [[JAXP>>http://en.wikipedia.org/wiki/Java_API_for_XML_Processing||rel="__blank"]]). As Xalan-J allows by default to execute Java code from the stylesheet, that's an easy to exploit vulnerability. Any logged-in user can execute arbitrary Java code in the context of the Web Application server (usually Tomcat) : [[CVE-2011-1571>>http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-1571||rel="__blank"]].
