Description

The remote host is running the Blazix web server, a web server written in Java.

The installed version of Blazix discloses the source code of its JSP pages by requesting the pages while appending a plus sign or a backslash to its name. An attacker may use this flaw to get the source code of your CGIs and possibly obtain passwords and other relevant information about this host.
