CVE-2024-47333

Vulnerability

Description

The Loops & Logic plugin for WordPress (versions through 4.1.4) contains a reflected Cross-Site Scripting (XSS) vulnerability due to improper neutralization of user-supplied input during web page generation [1]. This occurs because the plugin fails to sanitize or escape certain parameters before including them in output, allowing an attacker to inject malicious HTML or JavaScript code.

Exploitation

Prerequisites

Exploitation requires user interaction — a privileged user (such as an administrator) must click a crafted link, visit a specially crafted page, or submit a form that triggers the reflected payload [1]. The attacker does not need authenticated access to the target site, but the victim must be logged in with sufficient privileges for the injected script to execute in the context of the affected page.

Impact

Successful exploitation allows an attacker to inject arbitrary scripts that execute in the browser of the visiting user [1]. This can be used to redirect visitors to malicious sites, display unwanted advertisements, steal session cookies, or perform other actions within the security context of the vulnerable site. The vulnerability is considered moderately dangerous and is expected to be used in mass-exploit campaigns targeting thousands of WordPress installations [1].

Mitigation

The vulnerability has been addressed in version 4.1.5 of the plugin [1]. Users are strongly advised to update immediately. For those unable to update, Patchstack provides a mitigation rule that blocks attacks until a patched version can be applied [1].
