HTTP: Weblogic Malformed URL Reveal JSP Source
This signature detects attempts to exploit a known vulnerability in Bea Weblogic. Version V6.1 Service Pack 2 on Windows 2000 Server is vulnerable. Attackers can append the string "%00x" to a URL request to read the contents of a .jsp file.
Extended Description
Many webservers are case-sensitive, but do not have all possible combinations of cases in mapped extensions mapped properly. By changing the letters in a JSP or a JHTML file extension from lower case to upper case (eg: .jsp or .jhtml becomes .JSP or .JHTML) in a URL the server does not recognize the file extension and sends the file normally. In that manner, a user is able to access the source code to those specific files.
