At a glance
CVE-2022-4023 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the 3DPrint WordPress plugin, affecting versions <= 3.5.6.9. It carries a CVSS score of 8.1 (reachable over the network; low attack complexity; high confidentiality, integrity impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed September 2022, reported by WPScanTeam.
Vulnerability Overview
The 3DPrint plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.5.6.9. This is due to missing or incorrect nonce validation in the tinyfilemanager.php file. This makes it possible for unauthenticated attackers to create a backup of any file or directory on the site via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. File backups are stored with a predictable name (prepending a timestamp) in a known location which adds a trivial amount of complexity.
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. A successful exploit has high impact on confidentiality, integrity.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in 3DPrint <= 3.5.6.9 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. No fixed build of this plugin is recorded for 3DPrint yet, so installs running <= 3.5.6.9 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
The attempt arrives as an ordinary request to 3DPrint: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
