CVE-2024-47885

Summary

A DOM Clobbering gadget has been discoverd in Astro's client-side router. It can lead to cross-site scripting (XSS) in websites enables Astro's client-side routing and has stored attacker-controlled scriptless HTML elements (i.e., iframe tags with unsanitized name attributes) on the destination pages.

Details

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) living in the existing javascript code to transform it into executable code. More for information about DOM Clobbering, here are some references:

[1] https://scnps.co/papers/sp23_domclob.pdf [2] https://research.securitum.com/xss-in-amp4email-dom-clobbering/

Gadgets found in Astro

We identified a DOM Clobbering gadget in Astro's client-side routing module, specifically in the <ViewTransitions /> component. When integrated, this component introduces the following vulnerable code, which is executed during page transitions (e.g., clicking an <a> link):

https://github.com/withastro/astro/blob/7814a6cad15f06931f963580176d9b38aa7819f2/packages/astro/src/transitions/router.ts#L135-L156

However, this implementation is vulnerable to a DOM Clobbering attack. The document.scripts lookup can be shadowed by an attacker injected non-script HTML elements (e.g., <img name="scripts"><img name="scripts">) via the browser's named DOM access mechanism. This manipulation allows an attacker to replace the intended script elements with an array of attacker-controlled scriptless HTML elements.

The condition script.dataset.astroExec === '' on line 138 can be bypassed because the attacker-controlled element does not have a data-astroExec attribute. Similarly, the check on line 134 can be bypassed as the element does not require a type attribute.

Finally, the innerHTML of an attacker-injected non-script HTML elements, which is plain text content before, will be set to the .innerHTML of an script element that leads to XSS.

PoC

Consider a web application using Astro as the framework with client-side routing enabled and allowing users to embed certain scriptless HTML elements (e.g., form or iframe). This can be done through a bunch of website's feature that allows users to embed certain script-less HTML (e.g., markdown renderers, web email clients, forums) or via an HTML injection vulnerability in third-party JavaScript loaded on the page.

For PoC website, please refer to: https://stackblitz.com/edit/github-4xgj2d. Clicking the "about" button in the menu will trigger an alert(1) from an attacker-injected form element.

    <slot />
    <Footer />
    <script>
      import "../scripts/menu.js";
    </script>
  </body>
</html>

Impact

This vulnerability can result in cross-site scripting (XSS) attacks on websites that built with Astro that enable the client-side routing with ViewTransitions and store the user-inserted scriptless HTML tags without properly sanitizing the name attributes on the page.

Patch

We recommend replacing document.scripts with document.getElementsByTagName('script') for referring to script elements. This will mitigate the possibility of DOM Clobbering attacks leveraging the name attribute.

When `i18n.fallback` is configured, this new routing option controls whether to [redirect](https://docs.astro.build/en/guides/routing/#redirects) to the fallback page, or to [rewrite](https://docs.astro.build/en/guides/routing/#rewrites) the fallback page's content in place. The `"redirect"` option is the default value and matches the current behavior of the existing fallback system. The option `"rewrite"` uses the new [rewriting system](https://docs.astro.build/en/guides/routing/#rewrites) to create fallback pages that render content on the original, requested URL without a browser refresh. For example, the following configuration will generate a page `/fr/index.html` that will contain the same HTML rendered by the page `/en/index.html` when `src/pages/fr/index.astro` does not exist. ```js // astro.config.mjs export default defineConfig({ i18n: { locals: ['en', 'fr'], defaultLocale: 'en', routing: { prefixDefaultLocale: true, fallbackType: 'rewrite', }, fallback: { fr: 'en', }, }, }); ``` - [#11708](https://redirect.github.com/withastro/astro/pull/11708) [`62b0d20`](https://redirect.github.com/withastro/astro/commit/62b0d20b974dc932769221d210b751627fb4bbc6) Thanks [@martrapp](https://redirect.github.com/martrapp)! - Adds a new object `swapFunctions` to expose the necessary utility functions on `astro:transitions/client` that allow you to build custom swap functions to be used with view transitions.

` part of the page: ```html ``` See the [view transitions guide](https://docs.astro.build/en/guides/view-transitions/#astrobefore-swap) for more information about hooking into the `astro:before-swap` lifecycle event and adding a custom swap implementation. - [#11843](https://redirect.github.com/withastro/astro/pull/11843) [`5b4070e`](https://redirect.github.com/withastro/astro/commit/5b4070efef877a77247bb05a4806b75f22e557c8) Thanks [@bholmesdev](https://redirect.github.com/bholmesdev)! - Exposes `z` from the new `astro:schema` module.

Only static values are now supported (e.g. `export const prerender = true` or `= false`). This allows for better treeshaking and bundling configuration in the future. Adds a new [`"astro:route:setup"` hook](https://docs.astro.build/en/reference/integrations-reference/#astroroutesetup) to the Integrations API to allow you to dynamically set options for a route at build or request time through an integration, such as enabling [on-demand server rendering](https://docs.astro.build/en/guides/server-side-rendering/#opting-in-to-pre-rendering-in-server-mode). To migrate from a dynamic export to the new hook, update or remove any dynamic `prerender` exports from individual routing files: ```diff // src/pages/blog/[slug].astro - export const prerender = import.meta.env.PRERENDER ``` Instead, create an integration with the `"astro:route:setup"` hook and update the route's `prerender` option: ```js // astro.config.mjs import { defineConfig } from 'astro/config'; import { loadEnv } from 'vite'; export default defineConfig({ integrations: [setPrerender()], }); function setPrerender() { const { PRERENDER } = loadEnv(process.env.NODE_ENV, process.cwd(), ''); return { name: 'set-prerender', hooks: { 'astro:route:setup': ({ route }) => { if (route.component.endsWith('/blog/[slug].astro')) { route.prerender = PRERENDER; } }, }, }; } ``` - [#11360](https://redirect.github.com/withastro/astro/pull/11360) [`a79a8b0`](https://redirect.github.com/withastro/astro/commit/a79a8b0230b06ed32ce1802f2a5f84a6cf92dbe7) Thanks [@ascorbic](https://redirect.github.com/ascorbic)! - Adds a new [`injectTypes()` utility](https://docs.astro.build/en/reference/integrations-reference/#injecttypes-options) to the Integration API and refactors how type generation works Use `injectTypes()` in the `astro:config:done` hook to inject types into your user's project by adding a new a `*.d.ts` file. The `filename` property will be used to generate a file at `/.astro/integrations//.d.ts` and must end with `".d.ts"`. The `content` property will create the body of the file, and must be valid TypeScript. Additionally, `injectTypes()` returns a URL to the normalized path so you can overwrite its content later on, or manipulate it in any way you want. ```js // my-integration/index.js export default { name: 'my-integration', 'astro:config:done': ({ injectTypes }) => { injectTypes({ filename: 'types.d.ts', content: "declare module 'virtual:my-integration' {}", }); }, }; ``` Codegen has been refactored.

    Server island props are now encrypted with a key generated at build-time. This is intended to prevent accidentally leaking secrets caused by exposing secrets through prop-passing. This is not intended to allow a server island to be trusted to skip authentication, or to protect against any other vulnerabilities other than secret leakage.

-   [#11603](https://redirect.github.com/withastro/astro/pull/11603) [`f31d466`](https://redirect.github.com/withastro/astro/commit/f31d4665c1cbb0918b9e00ba1431fb6f264025f7) Thanks [@bholmesdev](https://redirect.github.com/bholmesdev)! - Improves user experience when render an Action result from a form POST request:

    -   Removes "Confirm post resubmission?" dialog when refreshing a result.
    -   Removes the `?_astroAction=NAME` flag when a result is rendered.

    Also improves the DX of directing to a new route on success. Actions will now redirect to the route specified in your `action` string on success, and redirect back to the previous page on error. This follows the routing convention of established backend frameworks like Laravel.

    For example, say you want to redirect to a `/success` route when `actions.signup` succeeds. You can add `/success` to your `action` string like so:

    ```astro
    
    ```

    -   On success, Astro will redirect to `/success`.
    -   On error, Astro will redirect back to the current page.

    You can retrieve the action result from either page using the `Astro.getActionResult()` function.

##### Note on security

This uses a temporary cookie to forward the action result to the next page. The cookie will be deleted when that page is rendered.

⚠ **The action result is not encrypted.** In general, we recommend returning minimal data from an action handler to a) avoid leaking sensitive information, and b) avoid unexpected render issues once the temporary cookie is deleted. For example, a `login` function may return a user's session id to retrieve from your Astro frontmatter, rather than the entire user object.
