Custom Content Types And Fields - SQL Injection (CVE-2023-6967)

Q: Am I affected by this vulnerability?

You are affected if your site runs Custom Content Types And Fields. Versions below 2.7.31.2 are vulnerable; that release and later are not.

Q: How do I fix it?

Update Custom Content Types And Fields to version 2.7.31.2 or later. That is the complete fix. 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 SQL Injection flaw. An attacker who exploits it can read, alter or delete anything in the site database, including user accounts and password hashes.

CVE-2023-6967

Vulnerability CVE-2023-6967 PLUGIN custom-content-types-and-fields HIGH

The Pods – Custom Content Types and Fields plugin for WordPress is vulnerable to SQL Injection via shortcode in all versions up to, and including, 3.0.10 (with the exception of 2.7.31.2, 2.8.23.2, 2.9.19.2) due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor level access or higher, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

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

Fix it

Update Custom Content Types And Fields to 2.7.31.2 or later.

That is the complete fix. Everything below is what protects you in the meantime.

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.
