At a glance

CVE-2023-25056 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Feed Them Social WordPress plugin, affecting versions <= 3.0.2. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 4.0.0; sites on affected versions should update now. Disclosed February 2023, reported by Rio Darmawan.

Vulnerability Overview

The Feed Them Social plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.0.2. This is due to missing or incorrect nonce validation on the following functions: fts_maybe_set_transient, fts_check_nag_get, feed_them_settings, social_follow_button, fts_facebook_page_form, fts_twitter_form, fts_instagram_form, fts_youtube_form, and fts_pinterest_form. This makes it possible for unauthenticated attackers to invoke those functions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Feed Them Social <= 3.0.2 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Feed Them Social the fix is 4.0.0: builds <= 3.0.2 are affected, anything from 4.0.0 onward is not.

Remediation

Update to version 4.0.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Feed Them Social: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Feed Them Social 4.0.0 closes this, and updating the plugin is the step that ends it.
