Description Preview
An attacker can exploit the CVE-2024-27983 vulnerability in Node.js HTTP/2 server by sending a small amount of HTTP/2 frames packets with a few HTTP/2 frames inside. This action can lead to leaving some data in nghttp2 memory after reset when headers with HTTP/2 CONTINUATION frame are sent to the server and then a TCP connection is abruptly closed by the client. This triggers the Http2Session destructor while header frames are still being processed and stored in memory, causing a race condition.
Overview
The vulnerability affects Node.js versions 18.20.0, 20.12.0, and 21.7.1. It has a CVSS v3.0 base score of 8.2, indicating a high severity issue. The vulnerability allows an attacker to make the Node.js HTTP/2 server completely unavailable by exploiting a race condition in the processing of HTTP/2 frames.
Remediation
To remediate the CVE-2024-27983 vulnerability, users are advised to update their Node.js installations to versions that have patched the issue. For affected versions 18.20.0, 20.12.0, and 21.7.1, it is recommended to upgrade to a version where the vulnerability has been fixed. Additionally, users should follow best practices for secure coding and server configurations to mitigate the risk of exploitation.
