At a glance
CVE-2022-3923 is a medium-severity Missing Authorization vulnerability in the ActiveCampaign for WooCommerce WordPress plugin, affecting versions <= 1.9.6. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 1.9.7; sites on affected versions should update now. Disclosed December 2022, reported by István Márton.
Vulnerability Overview
The ActiveCampaign plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the clear_wc_error_log function in versions up to, and including, 1.9.6. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to invoke this function via AJAX call resulting in log file deletion.
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. A successful exploit has high impact on integrity.
CWE-862: Missing Authorization
Reaching this weakness in ActiveCampaign for WooCommerce <= 1.9.6 takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For ActiveCampaign for WooCommerce the fix is 1.9.7: builds <= 1.9.6 are affected, anything from 1.9.7 onward is not.
Remediation
Update to version 1.9.7, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: ActiveCampaign for WooCommerce 1.9.7 closes this, and updating the plugin is the step that ends it.
