Red Hat Security Advisory 2013-0647-01 - JBoss Web is the web container, based on Apache Tomcat, in JBoss Enterprise Application Platform. It provides a single deployment platform for the JavaServer Pages and Java Servlet technologies. It was found that sending a request without a session identifier to a protected resource could bypass the Cross-Site Request Forgery prevention filter in JBoss Web. A remote attacker could use this flaw to perform CSRF attacks against applications that rely on the CSRF prevention filter and do not contain internal mitigation for CSRF. Multiple weaknesses were found in the JBoss Web DIGEST authentication implementation, effectively reducing the security normally provided by DIGEST authentication. A remote attacker could use these flaws to perform replay attacks in some circumstances.
