BEA WebLogic Scripts Server scripts Source Disclosure

Summary
BEA WebLogic may be tricked into revealing the source code of JSP scripts by using simple URL encoding of characters in the filename extension. e.g.: default.js%70 (=default.jsp) won't be considered as a script but rather as a simple document. Vulnerable systems: WebLogic version 5.1.0 SP 6 Immune systems: WebLogic version 5.1.0 SP 8
