follow-redirects' Proxy-Authorization header kept across hosts
When using axios, its dependency follow-redirects only clears authorization header during cross-domain redirect, but allows the proxy-authentication header which contains credentials too.
Steps To Reproduce & PoC
Test code:
const axios = require('axios');
axios.get('http://127.0.0.1:10081/', {
headers: {
'AuThorization': 'Rear Test',
'ProXy-AuthoriZation': 'Rear Test',
'coOkie': 't=1'
}
})
.then((response) => {
console.log(response);
})When I meet the cross-domain redirect, the sensitive headers like authorization and cookie are cleared, but proxy-authentication header is kept.
Impact
This vulnerability may lead to credentials leak.
Recommendations
Remove proxy-authentication header during cross-domain redirect
Recommended Patch
- removeMatchingHeaders(/^(?:authorization|cookie)$/i, this._options.headers);
+ removeMatchingHeaders(/^(?:authorization|proxy-authorization|cookie)$/i, this._options.headers);Software afectado
