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 unsanitizedname
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 atype
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
oriframe
). 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 analert(1)
from an attacker-injectedform
element.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 thename
attributes on the page.Patch
We recommend replacing
document.scripts
withdocument.getElementsByTagName('script')
for referring to script elements. This will mitigate the possibility of DOM Clobbering attacks leveraging thename
attribute.Reference

Thanks @matthewp! - Ensure we target scripts for execution in the routerUsing
document.scripts
is unsafe because if the application has aname="scripts"
this will shadow the built-indocument.scripts

Thanks @chaegumi! - Adds a newbuild.concurreny
configuration option to specify the number of pages to build in parallelIn most cases, you should not change the default value of
1
.Use this option only when other attempts to reduce the overall rendering time (e.g. batch or cache long running tasks like fetch calls or data access) are not possible or are insufficient.
Use this option only if the refactors are not possible. If the number is set too high, the page rendering may slow down due to insufficient memory resources and because JS is single-threaded.

toi18n.routing
configuration that allows you to control how fallback pages are handled.When
i18n.fallback
is configured, this new routing option controls whether to redirect to the fallback page, or to rewrite 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 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
whensrc/pages/fr/index.astro

Thanks @bholmesdev! - Improves user experience when render an Action result from a form POST request:?_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 whenactions.signup
succeeds. You can add/success
to youraction
string like so:/success
.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.v4.13.2
