CVE-2024-33946

Vulnerability

The WPify Woo Czech WordPress plugin, versions from n/a through 4.0.10, contains a reflected cross-site scripting (XSS) vulnerability [1]. Improper neutralization of user-controlled input during web page generation enables an attacker to inject arbitrary JavaScript [1]. The vulnerability affects all sites running the vulnerable versions of the plugin, which is used to extend WooCommerce for the Czech, Slovak, and EU markets [1].

Exploitation

An attacker can exploit this vulnerability by crafting a malicious URL with a payload that reflects back to the user without proper sanitization [1]. No authentication is required; the attacker only needs to trick a victim into clicking the crafted link or visiting a malicious page that triggers the request. The plugin does not apply sufficient output encoding or filtering on the reflected input [1].

Impact

Successful exploitation allows the attacker to execute arbitrary JavaScript in the context of the victim's browser [1]. This can lead to session hijacking, phishing attacks, defacement, or theft of sensitive data such as cookies or credentials. The attack can target any authenticated or unauthenticated user who interacts with the crafted link [1].

Mitigation

As of the available references, no fixed version is mentioned for WPify Woo Czech after 4.0.10 [1]. The latest version of the plugin is 5.4.5, but it is unclear whether it addresses this specific vulnerability [1]. Site administrators should update to the latest version of the plugin (currently 5.4.5) if available, and enable security measures such as Web Application Firewalls (WAF) to block reflected XSS attempts. Reviewing the plugin's input handling and applying proper escaping is recommended. No KEV listing is known at this time.
