At a glance

CVE-2023-47683 is a high-severity Improper Privilege Management vulnerability in the Social Login, Social Sharing by miniOrange WordPress plugin, affecting versions <= 7.6.6.

Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 7.6.7; sites on affected versions should update now. Disclosed November 2023, reported by Rafie Muhammad.

Vulnerability Overview

The WordPress Social Login and Register (Discord, Google, Twitter, LinkedIn) plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 7.6.6. This is due to the plugin improperly restricting user meta values that can be updated and allowing users to control a user role update during a social login through the custom registration form. This makes it possible for authenticated attackers, with subscriber-level access and above, to escalate their privileges to that of an administrator. We believe that this vulnerability requires the Custom Registration Add-on to be enabled, however, this is simply based on our assessment with the limited information available.

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 interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-269: Improper Privilege Management

Reaching this weakness in Social Login, Social Sharing by miniOrange <= 7.6.6 takes an account at Subscriber level or above. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Social Login, Social Sharing by miniOrange the fix is 7.6.7: builds <= 7.6.6 are affected, anything from 7.6.7 onward is not.

Remediation

Update to version 7.6.7, 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: Social Login, Social Sharing by miniOrange 7.6.7 closes this, and updating the plugin is the step that ends it.
