Can WebSockets be hijacked?

Also known as cross-origin WebSocket hijacking. It is a Cross-Site Request Forgery (CSRF) on a WebSocket handshake. It arises when the WebSocket handshake request relies solely on HTTP cookies for session handling and does not contain any CSRF tokens or other unpredictable values.

What is the impact of cross-site WebSocket hijacking?

What is the impact of cross-site WebSocket hijacking? A successful cross-site WebSocket hijacking attack will often enable an attacker to: Perform unauthorized actions masquerading as the victim user. As with regular CSRF, the attacker can send arbitrary messages to the server-side application.

How do I protect my WebSocket?

You should strongly prefer the secure wss:// protocol over the insecure ws:// transport. Like HTTPS, WSS (WebSockets over SSL/TLS) is encrypted, thus protecting against man-in-the-middle attacks. A variety of attacks against WebSockets become impossible if the transport is secured.

Can WebSocket set cookie?

Although, in theory, one could use cookies, as all WebSocket connections start with an HTTP request (with an upgrade header on it), and the cookies for the domain you are connecting to, will be sent with that initial HTTP request to open the WebSocket.

Are WebSockets a security risk?

Some WebSockets security vulnerabilities arise when an attacker makes a cross-domain WebSocket connection from a web site that the attacker controls. This is known as a cross-site WebSocket hijacking attack, and it involves exploiting a cross-site request forgery (CSRF) vulnerability on a WebSocket handshake.

What are the disadvantages of WebSockets?

The biggest downside to using WebSocket is the weight of the protocol and the hardware requirements that it brings with it. WebSocket requires a TCP implementation, which may or may not be a problem, but it also requires an HTTP implementation for the initial connection setup.

Are WebSockets blocked by Firewall?

WebSocket connections generally work even if a proxy or firewall is in place. This is because they use ports 80 and 443 which are also used by HTTP connections. In some situations WebSocket connections are blocked over port 80. In this case a secure SSL connection using WSS over port 443 should successfully connect.

Is WebSocket more secure than https?

wss is secure only because it means "WebSocket protocol over https". WebSocket protocol itself is not secure. There is no Secure WebSocket protocol, but there are just "WebSocket protocol over http" and "WebSocket protocol over https". See also this answer.

How many WebSockets is too many?

Using a WebSocket library of your choice to connect to the server. After the 10th connection no more connections are accepted by the server.

What will replace WebSockets?

WebTransport is a new specification that could offer an alternative to WebSockets. For applications that need low-latency, event-driven communication between endpoints, WebSockets has been the go-to choice, but WebTransport may change that.

Do WebSockets require TLS?

The wss protocol establishes a WebSocket over an encrypted TLS connection, while the ws protocol uses an unencrypted connection. At this point, the network connection remains open and can be used to send WebSocket messages in either direction.

Do WebSockets require HTTPS?

You can't use WebSockets over HTTPS, but you can use WebSockets over TLS (HTTPS is HTTP over TLS). Just use "wss://" in the URI. I believe recent version of Firefox won't let you use non-TLS WebSockets from an HTTPS page, but the reverse shouldn't be a problem.

Why WebSocket is not popular?

Websockets are largely obsolete because nowadays, if you create a HTTP/2 fetch request, any existing keepalive connection to that server is used, so the overhead that pre-HTTP/2 XHR connections needed is lost and with it the advantage of Websockets.

What is better than WebSockets?

Server-Sent Events is a good alternative to WebSockets for simple realtime use cases that only require one-way communication (from server to client). Examples include read-only realtime apps like stock tickers, or news updates.

Is WebSocket faster than HTTP?

All the frequently updated applications used WebSocket because it is faster than HTTP Connection. When we do not want to retain a connection for a particular amount of time or reuse the connection for transmitting data; An HTTP connection is slower than WebSockets.

What is WebSocket hijacking?

Cross-site WebSocket hijacking, also known as cross-origin WebSocket hijacking, involves a cross-site request forgery (CSRF) vulnerability on a WebSocket handshake.

Is WebSocket slower than TCP?

Thus, in most cases, it's probably not a good idea to use WebSockets instead of direct TCP since you'll get about 10 times higher message throughput with the latter (note that this is not the same as data throughput).

Can WebSockets be spoofed?

If you build your websocket over HTTP, then yes, it is completely possible for a third party to spoof the connection (and also to eavesdrop). If your HTTPS/WSS system does not properly validate certificates, then that also can be spoofed.

Are WebSockets blocked by Firewall?

WebSocket connections generally work even if a proxy or firewall is in place. This is because they use ports 80 and 443 which are also used by HTTP connections. In some situations WebSocket connections are blocked over port 80. In this case a secure SSL connection using WSS over port 443 should successfully connect.

Is WebSocket more secure than https?

wss is secure only because it means "WebSocket protocol over https". WebSocket protocol itself is not secure. There is no Secure WebSocket protocol, but there are just "WebSocket protocol over http" and "WebSocket protocol over https". See also this answer.

Can WebSocket messages get lost?

It can happen. TCP guarantees the order of packets, but it does not mean that all packets sent from a server reach a client even when an unrecoverable trouble happens in an underlying network.

What replaced WebSocket?

WebTransport is a new specification that could offer an alternative to WebSockets. For applications that need low-latency, event-driven communication between endpoints, WebSockets has been the go-to choice, but WebTransport may change that.

Do WebSockets require TLS?

The wss protocol establishes a WebSocket over an encrypted TLS connection, while the ws protocol uses an unencrypted connection. At this point, the network connection remains open and can be used to send WebSocket messages in either direction.

Why do WebSockets fail?

The “WebSocket unable to connect” error message indicates that you are likely working behind a proxy that doesn't support the WebSocket protocol. In this case, the device connections will switch to the HTTP protocol.

What is better than WebSockets?

Server-Sent Events is a good alternative to WebSockets for simple realtime use cases that only require one-way communication (from server to client). Examples include read-only realtime apps like stock tickers, or news updates.

Is WebSocket a TCP or HTTP?

The WebSocket protocol is an independent TCP-based protocol. Its only relationship to HTTP is that its handshake is interpreted by HTTP servers as an Upgrade request. By default the WebSocket protocol uses port 80 for regular WebSocket connections and port 443 for WebSocket connections tunneled over TLS [RFC2818].

Is WebSocket slower than TCP?

Thus, in most cases, it's probably not a good idea to use WebSockets instead of direct TCP since you'll get about 10 times higher message throughput with the latter (note that this is not the same as data throughput).

How many WebSockets is too many?

Using a WebSocket library of your choice to connect to the server. After the 10th connection no more connections are accepted by the server.

Why WebSockets are not scalable?

But why are WebSockets hard to scale? The main challenge is that connections to your WebSocket server need to be persistent. And even once you've scaled out your server nodes both vertically and horizontally, you also need to provide a solution for sharing data between the nodes.

Are WebSockets over TCP or UDP?

WebSocket is a computer communications protocol, providing full-duplex communication channels over a single TCP connection. The WebSocket protocol was standardized by the IETF as RFC 6455 in 2011.
