At a glance
CVE-2022-3923 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the ActiveCampaign for WooCommerce WordPress plugin, affecting versions <= 1.9.7. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires no authentication. The issue is fixed in version 1.9.8; sites on affected versions should update now. Disclosed December 2022, reported by István Márton.
Vulnerability Overview
The ActiveCampaign plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.9.7. This is due to missing or incorrect nonce validation on the clear_error_logs function. This makes it possible for unauthenticated attackers to delete the plugin's error logs, via forged request granted they can trick a site 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. A successful exploit has high impact on integrity.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in ActiveCampaign for WooCommerce <= 1.9.7 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. For ActiveCampaign for WooCommerce the fix is 1.9.8: builds <= 1.9.7 are affected, anything from 1.9.8 onward is not.
Remediation
Update to version 1.9.8, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to ActiveCampaign for WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: ActiveCampaign for WooCommerce 1.9.8 closes this, and updating the plugin is the step that ends it.
