DiracX-Web is vulnerable to attack through an Open Redirect on its login page
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | @dirac-grid/diracx-web-components | < 0.1.0-a8 | 0.1.0-a8 |
Details
As written in the advisory (Markdown source, shown as plain text).
### Summary
An attacker can forge a request to redirect an authenticated user to any arbitrary website.
### Details
On the login page, we have a `redirect` field which is the location where the server will redirect the user. This URI is not verified, and can be an arbitrary URI.
Paired with a parameter pollution, we can hide our malicious URI (ex: `https://dns.com/?param1=im_hidden_if_theres_lot_of_args?param1=bbb`).
### PoC
https://diracx-cert.app.cern.ch/auth?redirect=https://ipcim.com/en/where/?dsdsd=qsqsfsjfnsfniizaeiaapzqlalkqkaizqqijsjaopmqmxna?redirect=https://diracx-cert-app.cern.ch/auth
This POC can leak user's position.
### Impact
This could be used for phishing and extracting new data (such as redirecting to a new "log in" page, and asking users to reenter credentials).
