CVE-2017-12617

Al ejecutar Apache Tomcat desde la versión 9.0.0.M1 hasta la 9.0.0, desde la 8.5.0 hasta la 8.5.22, desde la 8.0.0.RC1 hasta la 8.0.46 y desde la 7.0.0 hasta la 7.0.81 con los HTTP PUT habilitados (por ejemplo, configurando el parámetro de inicialización de solo lectura del servlet Default a "false"), es posible subir un archivo JSP al servidor mediante una petición especialmente manipulada. Este JSP se puede después solicitar y cualquier código que contenga se ejecutaría por el servidor.

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.

Red Hat JBoss Enterprise Application Platform is a platform for Java applications based on the JBoss Application Server. This release of Red Hat JBoss Enterprise Application Platform 6.4.19 serves as a replacement for Red Hat JBoss Enterprise Application Platform 6.4.18, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References. Security Fix: It was found that when Artemis and HornetQ are configured with UDP discovery and JGroups discovery a huge byte array is created when receiving an unexpected multicast message. This may result in a heap memory exhaustion, full GC, or OutOfMemoryError.

When running Apache Tomcat, it is 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.
