CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2024-37890 – Denial of service when handling a request with many HTTP headers in ws
https://notcve.org/view.php?id=CVE-2024-37890
ws is an open source WebSocket client and server for Node.js. A request with a number of headers exceeding theserver.maxHeadersCount threshold could be used to crash a ws server. The vulnerability was fixed in ws@8.17.1 (e55e510) and backported to ws@7.5.10 (22c2876), ws@6.2.3 (eeb76d3), and ws@5.2.4 (4abd8f6). In vulnerable versions of ws, the issue can be mitigated in the following ways: 1. Reduce the maximum allowed length of the request headers using the --max-http-header-size=size and/or the maxHeaderSize options so that no more headers than the server.maxHeadersCount limit can be sent. 2. • https://github.com/websockets/ws/commit/22c28763234aa75a7e1b76f5c01c181260d7917f https://github.com/websockets/ws/commit/4abd8f6de4b0b65ef80b3ff081989479ed93377e https://github.com/websockets/ws/commit/e55e5106f10fcbaac37cfa89759e4cc0d073a52c https://github.com/websockets/ws/commit/eeb76d313e2a00dd5247ca3597bba7877d064a63 https://github.com/websockets/ws/issues/2230 https://github.com/websockets/ws/pull/2231 https://github.com/websockets/ws/security/advisories/GHSA-3h5v-q93c-6h6q https://nodejs.org/api/http.html#servermaxheaderscount https: • CWE-400: Uncontrolled Resource Consumption CWE-476: NULL Pointer Dereference •

aaugustin websockets version 4 contains a CWE-409: Improper Handling of Highly Compressed Data (Data Amplification) vulnerability in Servers and clients, unless configured with compression=None that can result in Denial of Service by memory exhaustion. This attack appear to be exploitable via Sending a specially crafted frame on an established connection. This vulnerability appears to have been fixed in 5. aaugustin websockets 4 contiene una vulnerabilidad CWE-409: gestión incorrecta de datos altamente comprimidos (amplificación de datos) en los servidores y los clientes, a no ser que se configure con compression=None, lo que puede resultar en una denegación de servicio (DoS) por agotamiento de memoria. Este ataque parece ser explotable mediante el envío de una trama especialmente manipulada en una conexión establecida. La vulnerabilidad parece haber sido solucionada en la versión 5. • https://github.com/aaugustin/websockets/pull/407 • CWE-400: Uncontrolled Resource Consumption •
