Since the plugin is designed to unify management of multiple sites on a server, an attacker can gain control over all sites serviced using InfiniteWP Client. To carry out the attack, it is sufficient to know the login of a user with administrator rights, after which a specially crafted POST request can be sent (<noindex><a rel=\"nofollow\" href=\"https:\/\/www.wordfence.com\/blog\/2020\/01\/critical-authentication-bypass-vulnerability-in-infinitewp-client-plugin\/\">by specifying<\/a><\/noindex> The parameter &laquo;add_site&raquo; or &laquo;readd_site&raquo; allows you to access the management interface with the privileges of this user.

The first vulnerability allows the contents of any DB tables to be reset to their initial state without authentication (bringing them to a fresh WordPress installation state, removing site-related data). This issue is caused by a lack of authorization checks during the reset function execution.\n<p>The second vulnerability in WP Database Reset requires authenticated access (it is sufficient to have an account with minimal subscriber rights) and allows gaining site administrator privileges (leading to the deletion of all users from the wp_users table, after which the remaining user will be treated as an administrator). The issues have been resolved in version 3.15.<\/p>\n<li class=\"l\"> <noindex><a rel=\"nofollow\" href=\"https:\/\/www.webarxsecurity.com\/vulnerability-infinitewp-client-wp-time-capsule\/\">The vulnerability<\/a><\/noindex> in the plugin <noindex><a rel=\"nofollow\" href=\"https:\/\/wordpress.org\/plugins\/wp-time-capsule\/\">WP Time Capsule<\/a><\/noindex>, which has over 20 thousand installations, allows connection with administrator rights without authentication.
