At a glance
CVE-2024-11943 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the 워드프레스 결제 심플페이 WordPress plugin, affecting versions <= 5.2.2. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 5.2.3; sites on affected versions should update now. Disclosed December 2024, reported by Peter Thaleikis.
Vulnerability Overview
The 워드프레스 결제 심플페이 – 우커머스 결제 플러그인 plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg() function without appropriate escaping on the URL in all versions up to, and including, 5.2.2. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
워드프레스 결제 심플페이 <= 5.2.2 carries this weakness at add_query_arg(), and reaching it takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For 워드프레스 결제 심플페이 the fix is 5.2.3: builds <= 5.2.2 are affected, anything from 5.2.3 onward is not.
Remediation
Update to version 5.2.3, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to 워드프레스 결제 심플페이: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: 워드프레스 결제 심플페이 5.2.3 closes this, and updating the plugin is the step that ends it.
