CyberRota Analysis
AI-GeneratedThe Single Sign On For TNG plugin for WordPress is critically vulnerable to an authentication bypass, allowing unauthenticated attackers to reset passwords for any user account, including administrators. This vulnerability arises from the `ssoprocess_ajax()` function, which improperly handles the password reset process without requiring ownership verification or email confirmation. WordPress site administrators and users of this plugin should prioritize immediate updates to mitigate the risk of unauthorized access and potential site takeover.
Original NVD Description
The Single Sign On For TNG plugin for WordPress is vulnerable to Authentication Bypass via unauthenticated password reset in all versions up to, and including, 2.0.0. This is due to the `ssoprocess_ajax()` function — registered on `wp_ajax_nopriv_ssoprocess_ajax` and therefore reachable without authentication — accepting an attacker-supplied `email` parameter with the `setnewpassword` operation and calling `reset_password()` on the resolved account without any ownership token, email confirmation link, or capability check. The sole guard is a call to `check_ajax_referer()`, which provides no authorization barrier because the `ssoajaxnonce` nonce is publicly broadcast on every front-end page via `wp_localize_script()` into the `SSOPWDREQUIREMENT` JavaScript object; since WordPress computes nonces for logged-out visitors against a shared anonymous session context, any unauthenticated visitor can scrape a valid nonce from the homepage and use it to authenticate the request. This makes it possible for unauthenticated attackers to change the password of any WordPress account, including administrator accounts, enabling complete site takeover.
