Boa Web Server versions 0.94.13 through 0.94.14 fail to validate the correct security constraint on the HEAD HTTP method allowing everyone to bypass the Basic Authorization mechanism.
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.
