Описание
Socket.IO enables bidirectional and low-latency communication for every platform. From 4.1.0 before 6.6.7, Engine.IO protocol v4 polling transport does not properly close the HTTP response for invalid binary POST requests with Content-Type: application/octet-stream, allowing an unauthenticated attacker to exhaust server-side connections and sockets. This issue is fixed in version 6.6.7.
A flaw was found in Socket.IO, specifically within the Engine.IO protocol v4 polling transport. An unauthenticated attacker can exploit this vulnerability by sending invalid binary POST requests with a Content-Type of application/octet-stream. This improper handling of requests prevents the HTTP response from being properly closed, which can lead to the exhaustion of server-side connections and sockets. The primary consequence is a Denial of Service (DoS), making the affected service unavailable to legitimate users.
Отчет
This flaw has been rated as Important. An unauthenticated remote attacker can exploit a vulnerability in the Engine.IO protocol v4 polling transport of Socket.IO by sending malformed binary POST requests. This can lead to server-side connection exhaustion and a denial of service, impacting the availability of applications utilizing Socket.IO.
