CVE-2024-51932

Vulnerability

Overview

The Kings Tab Slider plugin for WordPress, versions up to and including 1.0, contains a DOM-Based Cross-Site Scripting (XSS) vulnerability due to improper neutralization of user-supplied input during web page generation [1]. This flaw enables an attacker to inject arbitrary JavaScript or HTML into the plugin's output, which is then executed in the context of the victim's browser.

Exploitation

Details

Exploitation requires user interaction, specifically a privileged user (such as an administrator) to perform an action like clicking a malicious link, visiting a crafted page, or submitting a specially crafted form [1]. The attacker does not need direct access to the WordPress admin panel; instead, they can lure a privileged user into triggering the payload. The vulnerability is classified as DOM-Based, meaning the malicious script is executed client-side after the page loads, often bypassing server-side filters.

Impact

Successful exploitation allows an attacker to inject arbitrary scripts, which can be used to redirect visitors to malicious sites, display advertisements, steal session cookies, or deface the website [1]. This type of vulnerability is frequently leveraged in mass-exploit campaigns targeting thousands of WordPress sites regardless of their size or popularity [1].

Mitigation

As of the publication date, no patched version of the Kings Tab Slider plugin has been released. Users are strongly advised to update the plugin immediately if a newer version becomes available, or to remove the plugin entirely if it remains unmaintained [1]. For immediate protection, website administrators should consult their hosting provider or a web developer to implement workarounds such as web application firewall rules that block malicious input patterns.
