Vulnerability Details

This vulnerability allows remote attackers to bypass authentication on vulnerable installations of Oracle Application Testing Suite.

The specific flaw exists within the ActionServlet servlet. The process method for this servlet will bypass authentication if the URI starts with a specific string. By providing that string, and a directory traversal that follows it, an attacker is able to reach any URI that would map to that servlet without authentication.
