CVE-2024-5578
At a glance
CVE-2024-5578 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Table of Contents Plus WordPress plugin, affecting versions <= 2411. It carries a CVSS score of 5.5 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Editor level or above. The issue is fixed in version 2411.1; sites on affected versions should update now. Disclosed October 2024, reported by Dmitrii Ignatyev.
Vulnerability Overview
The Table of Contents Plus plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 2411 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
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.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Table of Contents Plus <= 2411 takes an account at Editor level or above. 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 Table of Contents Plus the fix is 2411.1: builds <= 2411 are affected, anything from 2411.1 onward is not.
Remediation
Update to version 2411.1, or a newer patched version
How does WordSec protect against this?
An attacker needs Editor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Table of Contents Plus 2411.1 closes this, and updating the plugin is the step that ends it.
