Описание
Socket.IO enables bidirectional and low-latency communication for every platform. From 6.5.0 before 6.6.7, Engine.IO servers with WebTransport enabled can resolve a crafted session ID such as proto through an inherited property of the clients object during WebTransport upgrade handling, causing a TypeError and denial of service. This issue is fixed in version 6.6.7.
A flaw was found in Engine.IO. When Engine.IO servers have WebTransport enabled, a remote attacker can craft a session ID to resolve an inherited property of the clients object during WebTransport upgrade handling. This can lead to a TypeError, resulting in a denial of service (DoS) for the server. This vulnerability impacts the availability of the service.
Отчет
This flaw has been rated as Important. When Engine.IO servers have WebTransport enabled, a remote attacker can trigger a denial of service. This occurs by sending a crafted session ID that resolves an inherited property during WebTransport upgrade handling, leading to a TypeError and impacting service availability.
