"The version of Oracle Secure Backup Administration Server running on
the remote host fails to adequately sanitize user-supplied input to
the 'uname' parameter of 'login.php'.  The system performs some
sanitization which limits exploitation of this issue, but code
execution is still possible.

A remote, unauthenticated attacker could exploit this to execute code
on the remote host with the privileges of the web server user.

By default the server runs with SYSTEM privileges under Windows."
