At a glance
CVE-2022-2383 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Feed Them Social WordPress plugin, affecting versions <= 2.9.9. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 3.0.1; sites on affected versions should update now. Disclosed July 2022, reported by dc11.
Vulnerability Overview
The Feed Them Social plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘access_token’ parameter in the function fts_refresh_token_ajax in versions up to, and including, 2.9.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts stored in the plugin options granted they can trick a site's 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Feed Them Social <= 2.9.9 carries this weakness at access_token, and reaching it takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Feed Them Social the fix is 3.0.1: builds <= 2.9.9 are affected, anything from 3.0.1 onward is not.
Remediation
Update to version 3.0.1, 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 3.0.1 closes this, and updating the plugin is the step that ends it.
