At a glance
CVE-2023-28618 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Enhanced Plugin Admin WordPress plugin, affecting versions <= 1.16. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.17; sites on affected versions should update now. Disclosed March 2023, reported by Yuki Haruma.
Vulnerability Overview
The Enhanced Plugin Admin plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.16. This is due to missing or incorrect nonce validation on the epa_options_page function. This makes it possible for unauthenticated attackers to update plugin settings via a 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.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Enhanced Plugin Admin <= 1.16 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 Enhanced Plugin Admin the fix is 1.17: builds <= 1.16 are affected, anything from 1.17 onward is not.
Remediation
Update to version 1.17, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Enhanced Plugin Admin: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Enhanced Plugin Admin 1.17 closes this, and updating the plugin is the step that ends it.
