CVE-2024-11464

Vulnerability

Description

The Easy Code Snippets plugin for WordPress is vulnerable to Reflected Cross-Site Scripting (XSS) in all versions up to and including 1.0.2 [1]. The vulnerability exists because the plugin fails to properly sanitize and escape the 'page' parameter before outputting it in the admin interface, allowing unauthenticated attackers to inject arbitrary JavaScript or HTML into the application's response [1].

Exploitation

Method

An attacker can exploit this flaw by crafting a malicious URL containing a specially crafted 'page' parameter. No authentication is required to trigger the vulnerability, but successful exploitation depends on social engineering—the victim must click a crafted link (e.g., in a phishing email or on a third-party site) [1]. The injected script then executes in the context of the victim's WordPress admin session.

Impact

Successful exploitation enables an attacker to perform actions such as stealing session cookies, modifying page content, or redirecting the victim to malicious sites. Because the plugin is typically used to manage code snippets, an attacker could also potentially escalate privileges if the victim is an administrator, leading to full site compromise.

Mitigation

The plugin was closed on December 6, 2024, and is no longer available for download due to this security issue [1]. Users who have installed version 1.0.2 or earlier should immediately remove or disable the plugin. No patch is available; the vendor recommended action is to switch to an alternative code-snippets solution.
