CVE-2024-42352
Nuxt is a free and open-source framework to create full-stack web applications and websites with Vue.js. nuxt/icon provides an API to allow client side icon lookup. This endpoint is at /api/_nuxt_icon/[name]. The proxied request path is improperly parsed, allowing an attacker to change the scheme and host of the request.
This leads to SSRF, and could potentially lead to sensitive data exposure. The new URL constructor is used to parse the final path. This constructor can be passed a relative scheme or path in order to change the host the request is sent to.
This constructor is also very tolerant of poorly formatted URLs. As a result we can pass a path prefixed with the string http:. This has the effect of changing the scheme to HTTP.
We can then subsequently pass a new host, for example http:127.0.0.1:8080. This would allow us to send requests to a local server. This issue has been addressed in release version 1.4.5 and all users are advised to upgrade.
