At a glance
CVE-2023-47757 is a medium-severity Missing Authorization vulnerability in the AWeber WordPress plugin, affecting versions <= 7.3.9. It carries a CVSS score of 6.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 7.3.10; sites on affected versions should update now. Disclosed November 2023, reported by Abdi Pranata.
Vulnerability Overview
The AWeber – Free Sign Up Form and Landing Page Builder Plugin for Lead Generation and Email Newsletter Growth plugin for WordPress is vulnerable to unauthorized access and modification of data due to a missing capability check on several functions hooked by AJAX actions in all versions up to, and including, 7.3.9. This makes it possible for subscribers and higher to create and publish pages and modify landing pages.
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.
CWE-862: Missing Authorization
Reaching this weakness in AWeber <= 7.3.9 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 AWeber the fix is 7.3.10: builds <= 7.3.9 are affected, anything from 7.3.10 onward is not.
Remediation
Update to version 7.3.10, 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: AWeber 7.3.10 closes this, and updating the plugin is the step that ends it.
