"According to its self-reported version number, the Atlassian Confluence application running on the remote host is prior
to 7.4.2 or 7.5.x prior to 7.5.2. It is, therefore, affected by a cross-site scripting (XSS) vulnerability in user macro
parameters. An authenticated, remote attacker can exploit this to inject HTML and JavaScript to execute arbitrary script
code in a user's browser session.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
