Cf7 Styler - Cross-Site Scripting (XSS) (CVE-2024-12419)

Q: Am I affected by this vulnerability?

You are affected if your site runs Cf7 Styler. No account is needed to exploit this, so a public site is reachable by anyone.

Q: How do I fix it?

Update Cf7 Styler to the latest available version. Where the vendor has not yet published a fix, remove or disable the plugin until they do. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

Q: What can an attacker actually do?

This is a Cross-Site Scripting (XSS) flaw. An attacker who exploits it can run script in a visitor's browser, stealing sessions or planting an administrator account.

CVE-2024-12419

Vulnerability CVE-2024-12419 PLUGIN cf7-styler MEDIUM

The The Design for Contact Form 7 Style WordPress Plugin – CF7 WOW Styler plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 1.7.0. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. This functionality is also vulnerable to Reflected Cross-Site Scripting. Version 1.7.0 patched the Reflected XSS issue, however, the arbitrary shortcode execution issue remains.

What to do about this

Patch promptly The consequence is significant even where an attacker needs a foothold first.

Fix it

Update Cf7 Styler to the latest available version.

Where the vendor has not published a fix yet, disable the plugin until they do.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.
