Macromedia JRun 3.0 through 4.0, when running on Windows, allows remote attackers to retrieve files in the WEB-INF directory, which contains Java class files and configuration information, via a request to the WEB-INF directory with a trailing dot ("WEB-INF.").
Heap-based buffer overflow in the error-handling mechanism for the IIS ISAPI handler in Macromedia JRun 4.0 and earlier allows remote attackers to execute arbitrary via an HTTP GET request with a long .jsp file name.
The Java Server Pages (JSP) engine in JRun allows web page owners to cause a denial of service (engine crash) on the web server via a JSP page that calls WPrinterJob().pageSetup(null,null).
JRun 3.0 through 4.0 allows remote attackers to read JSP source code via an encoded null byte in an HTTP GET request, which causes the server to send the .JSP file unparsed.
