CVE-2024-47068 is a medium-severity vulnerability affecting Rollup, a popular module bundler for JavaScript. This vulnerability allows for a DOM Clobbering attack when bundling scripts that utilize properties from `import.meta`, such as `import.meta.url`, in various formats like `cjs`, `umd`, and `iife`. Specifically, versions prior to 2.79.2, 3.29.5, and 4.22.4 are at risk. Attackers may leverage this vulnerability to execute cross-site scripting (XSS) attacks in web pages that contain attacker-controlled HTML elements, such as an `img` tag with an unsanitized `name` attribute.
The vulnerability was officially reported on September 23, 2024, and was classified under CWE-79, which pertains to improper neutralization of input during web page generation, leading to XSS. Given the nature of this vulnerability and its potential impact, organizations using affected versions of Rollup should take immediate action to patch their systems.
With a CVSS score of 6.1, this vulnerability falls into the medium severity category, indicating that it presents a moderate risk to organizations. The attack vector is network-based, and the vulnerability requires user interaction, which enhances the potential for exploitation. Organizations should prioritize patching immediately to mitigate the risk of exploitation.
As a precaution, users of Rollup should validate their installations to ensure they are running on patched versions: Rollup 2.79.2, 3.29.5, or 4.22.4. If not, they must upgrade as part of their security best practices.
Vulnerability Details
The official description of this vulnerability states that it enables DOM Clobbering, which facilitates the manipulation of the Document Object Model in a way that can lead to XSS attacks. The affected versions of Rollup include all releases prior to 2.79.2, 3.29.5, and 4.22.4, which contain the necessary patches.
Technical Analysis
The root cause of the vulnerability lies in the way Rollup handles scripts when bundling modules that rely on `import.meta`. The attack vector is network-based, and the complexity of the attack is low, meaning that it does not require advanced skills to exploit. Importantly, no privileges are required to exploit this issue, but user interaction is necessary, as the attacker must trick users into visiting a maliciously crafted page.
The impacts of the vulnerability include low confidentiality and integrity impacts, as the attacker can manipulate the page's content, potentially leading to unauthorized data exposure or modifications. The availability impact is none, so the primary concern is around confidentiality and integrity.
Risk & Impact Analysis
Organizations using vulnerable versions of Rollup are at risk of XSS attacks, which can compromise sensitive user data and lead to further attacks such as credential theft or session hijacking. The blast radius of such attacks can be significant, especially for web applications handling sensitive user input or data.
Given the CVSS score of 6.1, organizations should address this vulnerability in their priority patch cycle. The risk of exploitation is medium, and timely remediation is essential to safeguard against potential exploitation in the wild.
