Foundstone Security Advisory FS-073100-10-BEA - It is possible to compile and execute any arbitrary file within the web document root directory of the WebLogic server as if it were a JSP/JHTML file, even if the file type is not .jsp or .jhtml. If applications residing on the WebLogic server write to files within the web document root directory, it is possible to insert executable code in the form of JSP or JHTML tags and have the code compiled and executed using WebLogic's handlers. This can potentially cause an attacker to gain administrative control of the underlying operating systems.
