[VU:715737] Mozilla-based browsers jar: URI cross-site scripting vulnerability

Overview

Mozilla-based web browsers including Firefox contain a vulnerability that may allow an attacker to execute code, or conduct cross-site scripting attacks.

Impact

This vulnerability may allow an attacker to execute cross-site scripting attacks on sites that allow users to upload pictures, archives, or other files.

Solution

This vulnerability is addressed in Mozilla Firefox 2.0.0.10: From MFSA 2007-37: Support for the jar: URI scheme has been restricted to files served with a Content-Type header of application/java-archive or application/x-jar. Web applications that require signed pages must make sure their .jar archives are served with this Content-Type. Sites that allow users to upload binary files should make sure they do not allow these files to have one of these two MIME types.
