Node.js HTTP Servers Vulnerable to Resource Exhaustion Attacks

CVE-2024-22019

What is CVE-2024-22019?

A vulnerability exists within Node.js HTTP servers that permits attackers to send specially crafted HTTP requests utilizing chunked encoding. This manipulation can lead to resource exhaustion, as the server is induced to read an unbounded number of bytes from a single connection. The flaw takes advantage of insufficient limitations on chunk extension bytes, which can result in the depletion of CPU resources and network bandwidth. Consequently, this vulnerability allows attackers to bypass traditional safeguards such as timeout settings and body size limits, ultimately causing denial of service conditions.
