K000139558 : Node.js vulnerabilities CVE-2023-46809, CVE-2024-21892, and CVE-2024-22019

Security Advisory Description

• CVE-2023-46809

This candidate has been reserved by a CVE Numbering Authority (CNA). This record will be updated by the assigning CNA once details are available. Learn more about the Reserved state here.

• CVE-2024-21892

On Linux, Node.js ignores certain environment variables if those may have been set by an unprivileged user while the process is running with elevated privileges with the only exception of CAP_NET_BIND_SERVICE. Due to a bug in the implementation of this exception, Node.js incorrectly applies this exception even when certain other capabilities have been set. This allows unprivileged users to inject code that inherits the process’s elevated privileges.

• CVE-2024-22019

A vulnerability in Node.js HTTP servers allows an attacker to send a specially crafted HTTP request with chunked encoding, leading to resource exhaustion and denial of service (DoS). The server reads an unbounded number of bytes from a single connection, exploiting the lack of limitations on chunk extension bytes. The issue can cause CPU and network bandwidth exhaustion, bypassing standard safeguards like timeouts and body size limits.
