CVE-2024-22019 – nodejs: reading unprocessed HTTP request with unbounded chunk extension allows DoS attacks

https://notcve.org/view.php?id=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. Una vulnerabilidad en los servidores HTTP de Node.js permite a un atacante enviar una solicitud HTTP especialmente manipulada con codificación fragmentada, lo que provoca el agotamiento de los recursos y la denegación de servicio (DoS). El servidor lee una cantidad ilimitada de bytes de una única conexión, aprovechando la falta de limitaciones en los bytes de extensión de fragmentos. • http://www.openwall.com/lists/oss-security/2024/03/11/1 https://hackerone.com/reports/2233486 https://security.netapp.com/advisory/ntap-20240315-0004 https://access.redhat.com/security/cve/CVE-2024-22019 https://bugzilla.redhat.com/show_bug.cgi?id=2264574 • CWE-400: Uncontrolled Resource Consumption •
