Описание
When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.
A vulnerability was discovered in Tomcat where if a servlet context was configured with readonly=false and HTTP PUT requests were allowed, an attacker could upload a JSP file to that context and achieve code execution.
Отчет
This flaw affects Tomcat on Red Hat Enterprise Linux only when a specific context is configured with readonly=false. The default configuration has a readonly context, so it is not affected.
Меры по смягчению последствий
Ensure that readonly is set to true (the default) for the DefaultServlet, WebDAV servlet or application context. Block HTTP methods that permit resource modification for untrusted users.
