Overview

Bootstrap is an HTML, CSS, and JS framework for developing responsive, mobile-first web sites and applications.

‍

A cross-site scripting (XSS) vulnerability (CVE-2024-6484) has been identified within the Bootstrap 3 Carousel component.

‍

Per OWASP: Cross-Site Scripting attacks are a type of injection, in which malicious scripts are injected into otherwise benign and trusted websites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user. An attacker can use XSS to send a malicious script to an unsuspecting user.

Vulnerability Info

An anchor element (<a>), when used for carousel navigation with a data-slide or data-slide-to attribute, can contain an href attribute value that is not subject to proper content sanitization. Improper extraction of the intended target carousel’s #id from the href attribute can lead to use cases where the click event’s preventDefault() is not applied and the href is evaluated and executed. As a result, restrictions are not applied to the data that is evaluated, which can lead to potential XSS vulnerabilities.
