Security-Assessment.com has reported some vulnerabilities in Oracle GlassFish Enterprise Server, which can be exploited by malicious people to conduct cross-site scripting and request forgery attacks.

1) The application allows users to perform certain actions via HTTP requests without performing proper validity checks to verify the requests. This can be exploited to e.g. uploading an arbitrary WAR archive by tricking a logged-in administrator into visiting a specially crafted web page.

2) Input passed via multiple parameters to various scripts is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerabilities are reported in version 3.1.1 (build 12). Other versions may also be affected.

Solution
Apply patch (please see the vendor's advisory for details).
