CVE-2019-6703
At a glance
CVE-2019-6703 is a critical-severity Missing Authorization vulnerability in the Total Donations WordPress plugin, affecting versions <= 2.0.5. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.0.0; sites on affected versions should update now. Disclosed January 2019, reported by Ram.
Vulnerability Overview
Incorrect access control in migla_ajax_functions.php in the Calmar Webmedia Total Donations plugin through 2.0.5 for WordPress allows unauthenticated attackers to update arbitrary WordPress option values, leading to site takeover. These attackers can send requests to wp-admin/admin-ajax.php to call the miglaA_update_me action to change arbitrary options on affected sites. This can be used to enable new user registration and set the default role for new users to Administrator.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-862: Missing Authorization
Reaching this weakness in Total Donations <= 2.0.5 takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Total Donations the fix is 3.0.0: builds <= 2.0.5 are affected, anything from 3.0.0 onward is not.
Remediation
Update to version 3.0.0, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Total Donations 3.0.0 closes this, and updating the plugin is the step that ends it.
