At a glance
CVE-2023-4703 is a critical-severity Improper Privilege Management vulnerability in the All in One B2B for WooCommerce WordPress plugin, affecting versions <= 1.0.3. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed September 2023, reported by Alexander Concha.
Vulnerability Overview
The All in One B2B for WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 1.0.3. This is due to insufficient validation of certain parameters when updating user details. This makes it possible for unauthenticated attackers update the details of any user (e.g., password) to gain elevated privileges.
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, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-269: Improper Privilege Management
Reaching this weakness in All in One B2B for WooCommerce <= 1.0.3 takes no account at all. Improper privilege management means the code lets an account end up with capabilities its role should not have.
It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. No fixed build of this plugin is recorded for All in One B2B for WooCommerce yet, so installs running <= 1.0.3 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?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
