發布日:2024/9/26修改日:2025/8/15

描述

### Summary A DOM Clobbering vulnerability has been discovered in `layui` that can lead to Cross-site Scripting (XSS) on web pages where attacker-controlled HTML elements (e.g., `img` tags with unsanitized `name` attributes) are present. It's worth noting that we’ve identifed similar issues in other popular client-side libraries like Webpack ([CVE-2024-43788](https://github.com/webpack/webpack/security/advisories/GHSA-4vvj-4cpr-p986)) and Vite ([CVE-2024-45812](https://github.com/vitejs/vite/security/advisories/GHSA-64vr-g452-qvp3)), which might serve as valuable references. ### Backgrounds DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script, seemingly benign HTML markups in the webpage (e.g. through a post or comment) and leverages the gadgets (pieces of js code snippet) living in the existing libraries to transform it into executable code. ### Impact This vulnerability can lead to cross-site scripting (XSS) on websites that uses `layui` library and allow users to inject certain scriptless HTML tags with improperly sanitized `name` or `id` attributes. ### Patch This problem has been patched in Layui 2.9.17.
