java/org/apache/catalina/servlets/DefaultServlet.java in the default
servlet in Apache Tomcat before 6.0.40, 7.x before 7.0.53, and 8.x before
8.0.4 does not properly restrict XSLT stylesheets, which allows remote

via a crafted web application that provides an XML external entity
declaration in conjunction with an entity reference, related to an XML
External Entity (XXE) issue.
