DISPUTED Boa 0.94.13 allows remote attackers to obtain sensitive
information via a misconfiguration involving backup.html, preview.html,
js/log.js, log.html, email.html, online-users.html, and config.js. NOTE:
multiple third parties report that this is a site-specific issue because
those files are not part of Boa.

Notes

Author Note
seth-arnold I believe this just means there’s no limits on who can access those files. I didn’t find better descriptions elsewhere, and it looks like a dead project.
