4.5.2->4.5.5GitHub Vulnerability Alerts
CVE-2024-31207
Summary
Vite dev server option
server.fs.denydid not deny requests for patterns with directories. An example of such a pattern is/foo/**/*.Impact
Only apps setting a custom
server.fs.denythat includes a pattern with directories, and explicitly exposing the Vite dev server to the network (using--hostorserver.hostconfig option) are affected.Patches
Fixed in [email protected], [email protected], [email protected], [email protected], [email protected], [email protected]
Details
server.fs.denyuses picomatch with the config of{ matchBase: true }. matchBase only matches the basename of the file, not the path due to a bug (https://github.com/micromatch/picomatch/issues/89). The vite config docs read like you should be able to set fs.deny to glob with picomatch. Vite also does not set{ dot: true }and that causes dotfiles not to be denied unless they are explicitly defined.Reproduction
Set fs.deny to
['**/.git/**']and then curl for/.git/config.matchBase: true, you can get any file under.git/(config, HEAD, etc).matchBase: false, you cannot get any file under.git/(config, HEAD, etc).CVE-2024-45811
Summary
The contents of arbitrary files can be returned to the browser.
Details
@fsdenies access to files outside of Vite serving allow list. Adding?import&rawto the URL bypasses this limitation and returns the file content if it exists.PoC
CVE-2024-45812
Summary
We discovered a DOM Clobbering vulnerability in Vite when building scripts to
cjs/iife/umdoutput format. The DOM Clobbering gadget in the module can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements (e.g., an img tag with an unsanitized name attribute) are present.Note that, we have identified similar security issues in Webpack: GHSA-4vvj-4cpr-p986
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 Vite
We have identified a DOM Clobbering vulnerability in Vite bundled scripts, particularly when the scripts dynamically import other scripts from the assets folder and the developer sets the build output format to
cjs,iife, orumd. In such cases, Vite replaces relative paths starting with__VITE_ASSET__using the URL retrieved fromdocument.currentScript.However, this implementation is vulnerable to a DOM Clobbering attack. The
document.currentScriptlookup can be shadowed by an attacker via the browser's named DOM tree element access mechanism. This manipulation allows an attacker to replace the intended script element with a malicious HTML element. When this happens, the src attribute of the attacker-controlled element is used as the URL for importing scripts, potentially leading to the dynamic loading of scripts from an attacker-controlled server.PoC
Considering a website that contains the following
main.jsscript, the devloper decides to use the Vite to bundle up the program with the following configuration.After running the build command, the developer will get following bundle as the output.
Adding the Vite bundled script,
dist/index-DDmIg9VD.js, as part of the web page source code, the page could load theextra.jsfile from the attacker's domain,attacker.controlled.server. The attacker only needs to insert animgtag with thenameattribute set tocurrentScript. This can be done through a 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.Impact
This vulnerability can result in cross-site scripting (XSS) attacks on websites that include Vite-bundled files (configured with an output format of
cjs,iife, orumd) and allow users to inject certain scriptless HTML tags without properly sanitizing the name or id attributes.Patch
