At a glance

This record tracks a critical-severity Authentication Bypass Using an Alternate Path or Channel vulnerability in the Social Share, Social Login and Social Comments Plugin WordPress plugin, affecting versions <= 7.10.6. 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 7.11; sites on affected versions should update now. Disclosed March 2018.

Vulnerability Overview

The Social Share, Social Login and Social Comments plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the 'the_champ_user_auth' AJAX action in versions up to, and including, 7.10.6. This makes it possible for unauthenticated attackers to log in as any user, assuming they know their email address.

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-288: Authentication Bypass Using an Alternate Path or Channel

Social Share, Social Login and Social Comments Plugin <= 7.10.6 carries this weakness at the_champ_user_auth, and reaching it takes a caller who can reach the endpoint. Authentication bypass through an alternate path means the application has a second route to a protected action that skips the checks the primary route performs.

The protection on the main path becomes irrelevant, because the attacker simply uses the route that never asks. For Social Share, Social Login and Social Comments Plugin the fix is 7.11: builds <= 7.10.6 are affected, anything from 7.11 onward is not.

Remediation

Update to version 7.11, 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 Share, Social Login and Social Comments Plugin 7.11 closes this, and updating the plugin is the step that ends it.
