Allaire JRun 2.3.3, 3.0 and 3.1 running on IIS 4.0 and 5.0, iPlanet, Apache, JRun web server (JWS), and possibly other web servers allows remote attackers to read arbitrary files and directories by appending (1) "%3f.jsp", (2) "?.jsp" or (3) "?" to the requested URL.

Cross-site scripting vulnerability in Allaire JRun 3.0 and 2.3.3 allows a malicious webmaster to embed Javascript in a request for a .JSP, .shtml, .jsp10, .jrun, or .thtml file that does not exist, which causes the Javascript to be inserted into an error message.

SSIFilter in Allaire JRun 3.1, 3.0 and 2.3.3 allows remote attackers to obtain source code for Java server pages (.jsp) and other files in the web root via an HTTP request for a non-existent SSI page, in which the request's body has an #include statement.
