"The third-party Open Flash Chart component included with the version
of OpenX hosted on the remote web server allows an unauthenticated
attacker to upload arbitrary files to the affected system, by default
in a web-accessible directory.

While Nessus has not verified this, it is likely that an attacker
could exploit this to upload a script with, say, PHP code and then
browse to that file, causing arbitrary code to be executed on the
remote system subject to the privileges of the web server user id.");
