Detects Vulnerability in the execution of JSPs outside doc_root. A potential security vulnerability has been discovered in Oracle JSP releases 1.0.x through 1.1.1 (in Apache/Jserv). This vulnerability permits access to and execution of unintended JSP files outside the doc_root in Apache/Jserv. For example, accessing http://www.example.com/a.jsp//..//..//..//..//..//../b.jsp will execute b.jsp outside the doc_root instead of a.jsp if there is a b.jsp file in the matching directory. Further, Jserv Releases 1.0.x - 1.0.2 have additional vulnerability: Due to a bug in Apache/Jserv path translation, any URL that looks like: http://host:port/servlets/a.jsp, makes Oracle JSP execute 'd:\servlets\a.jsp' if such a directory path actually exists. Thus, a URL virtual path, an actual directory path and the Oracle JSP name (when using Oracle Apache/JServ) must match for this potential vulnerability to occur. Vulnerable systems: Oracle8i Release 8.1.7, iAS Release version 1.0.2 Oracle JSP, Apache/JServ Releases version 1.0.x - 1.1.1

Upgrade to OJSP Release 1.1.2.0.0, available on Oracle Technology Network's OJSP web site.
