JBoss Web Server (jbossweb) is an enterprise ready web server designed for medium and large applications, is based on Apache Tomcat, and is embedded into JBoss Application Server. It provides organizations with a single deployment platform for JavaServer Pages (JSP) and Java Servlet technologies, Microsoft .NET, PHP, and CGI. A traversal vulnerability was discovered when using a RequestDispatcher in combination with a servlet or JSP. A remote attacker could utilize a specially-crafted request parameter to access protected web resources. (CVE-2008-2370) An additional traversal vulnerability was discovered when the "allowLinking" and "URIencoding" settings were activated. A remote attacker could use a UTF-8-encoded request to extend their privileges and obtain local files accessible to the jbossweb process. (CVE-2008-2938) Users of jbossweb should upgrade to this updated package, which contains backported patches to resolve these issues.
