CVE-2024-47380

Vulnerability

Overview CVE-2024-47380 is a reflective cross-site scripting (XSS) vulnerability found in the WP-Lister Lite for eBay WordPress plugin, affecting versions from n/a through 3.6.3. The root cause is Improper Neutralization of Input During Web Page Generation, meaning user-supplied data is reflected back to the browser without proper sanitization or encoding [1].

Exploitation

Prerequisites Exploitation requires user interaction: an attacker must trick a privileged user (such as an administrator) into clicking a crafted malicious link, visiting a specially designed page, or submitting a form. The attacker does not require any authentication or special network position, as the attack can be delivered via email, social engineering, or other channels leading to the vulnerable plugin's interface [1].

Impact

If successfully exploited, the attacker can inject arbitrary HTML and JavaScript code into the context of the victim's browser session. This can lead to redirecting users to malicious sites, displaying unwanted advertisements, stealing session cookies, or performing actions on behalf of the victim within the WordPress admin panel. The CVSS v3 score of 7.1 (High) reflects the potential for significant harm, especially given that this type of vulnerability is frequently used in mass-exploit campaigns targeting thousands of websites simultaneously [1].

Mitigation

The vendor has released a patched version 3.6.5 that resolves the vulnerability. Users are strongly advised to update to version 3.6.5 or later immediately. For those unable to update, Patchstack recommends applying a virtual mitigation rule that blocks exploitation attempts until the plugin is updated. As this vulnerability is considered moderately dangerous and expected to be exploited, immediate action is required [1].
