A new security vulnerability in miniOrange WordPress Social Login and Register (Discord, Google, Twitter, and LinkedIn) has been discovered and assigned the identifier CVE-2023-25455. This Missing Authorization vulnerability allows attackers to exploit incorrectly configured access control security levels within the plugin, potentially leading to unauthorized access to sensitive user information. This post aims to provide an in-depth analysis of the vulnerability, information about affected versions and links to original references, as well as a detailed explanation of the exploit and how to protect your WordPress site from this security risk.
Affected Versions
This security vulnerability affects the miniOrange WordPress Social Login and Register (Discord, Google, Twitter, LinkedIn) plugin for any version from "n/a" to "7.6.".
The Exploit
The Missing Authorization vulnerability identified as CVE-2023-25455 in the miniOrange WordPress Social Login and Register plugin allows an attacker to bypass the required proper access right and gain unauthorized access to user accounts and sensitive information. This is due to insufficient restrictions on which roles can access specific resources within the plugin.
Here's a code snippet that demonstrates the vulnerability
function mo_oauth_check_login() {
if (!is_user_logged_in()) {
$user = get_user_by('login', 'admin');
if (!$user) {
return;
}
wp_set_current_user($user->ID, $user->user_login);
wp_set_auth_cookie($user->ID);
do_action('wp_login', $user->user_login);
}
}
This code sample shows that the 'mo_oauth_check_login()' function allows access to the user account without actually validating the user. An attacker could exploit this by changing the 'admin' parameter in the 'get_user_by()' function to any other user without proper authentication.
