Advisory
Source description from Wordfence Intelligence, credited to Kévin Mosbahi (Mika).
The Under Construction / Maintenance Mode from Acurax plugin for WordPress is vulnerable to IP Address Spoofing in all versions up to, and including, 2.6 due to insufficient IP address validation and/or use of user-supplied HTTP headers as a primary method for IP retrieval. This makes it possible for unauthenticated attackers to bypass controls.
