Cross-site scripting (XSS) vulnerability in the Management Console in JRun 4.0 allows remote attackers to execute arbitrary web script or HTML and possibly hijack a user's session.

JRun 4.0 does not properly generate and handle the JSESSIONID, which allows remote attackers to perform a session fixation attack and hijack a user's HTTP session.

Buffer overflow in the WriteToLog function for JRun 3.0 through 4.0 web server connectors, such as (1) mod_jrun and (2) mod_jrun20 for Apache, with verbose logging enabled, allows remote attackers to execute arbitrary code via a long HTTP header Content-Type field or other fields.

The Microsoft IIS Connector in JRun 4.0 and Macromedia ColdFusion MX 6.0, 6.1, and 6.1 J2EE allows remote attackers to bypass authentication and view source files, such as .asp, .pl, and .php files, via an HTTP request that ends in ";.cfm".

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.").

Macromedia JRun 3.0, 3.1, and 4.0 allow remote attackers to view the source code of .JSP files via Unicode encoded character values in a URL.

Unknown "file disclosure" vulnerability in Macromedia JRun 3.0, 3.1, and 4.0, related to a log file or jrun.ini, with unknown impact.

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.

Buffer overflow in the ISAPI DLL filter for Macromedia JRun 3.1 allows remote attackers to execute arbitrary code via a direct request to the filter with a long HTTP host header field in a URL for a .jsp file.

Macromedia JRun Administration Server allows remote attackers to bypass authentication on the login form via an extra slash (/) in the URL.

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.

JRun 3.0 and 3.1 running on JRun Web Server (JWS) and IIS allows remote attackers to read arbitrary JavaServer Pages (JSP) source code via a request URL containing the source filename ending in (1) "jsp%00" or (2) "js%2570".

Macromedia JRun 3.0 and 3.1 allows remote attackers to obtain duplicate active user session IDs and perform actions as other users via a URL request for the web application directory without the trailing '/' (slash), as demonstrated using ctx.

Directory traversal vulnerability in Macromedia JRun Web Server (JWS) 2.3.3, 3.0 and 3.1 allows remote attackers to read arbitrary files via a .. (dot dot) in the HTTP GET request.

Macromedia JRun 3.0 and 3.1 appends the jsessionid to URL requests (a.k.a. rewriting) when client browsers have cookies enabled, which allows remote attackers to obtain session IDs and hijack sessions via HTTP referrer fields or sniffing.

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.

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.

Allaire JRun 3.0 allows remote attackers to list contents of the WEB-INF directory, and the web.xml file in the WEB-INF directory, via a malformed URL that contains a "."
