CVE-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 •
CVE-2021-32640 – ReDoS in Sec-Websocket-Protocol header
https://notcve.org/view.php?id=CVE-2021-32640
ws is an open source WebSocket client and server library for Node.js. A specially crafted value of the `Sec-Websocket-Protocol` header can be used to significantly slow down a ws server. The vulnerability has been fixed in ws@7.4.6 (https://github.com/websockets/ws/commit/00c425ec77993773d823f018f64a5c44e17023ff). In vulnerable versions of ws, the issue can be mitigated by reducing the maximum allowed length of the request headers using the [`--max-http-header-size=size`](https://nodejs.org/api/cli.html#cli_max_http_header_size_size) and/or the [`maxHeaderSize`](https://nodejs.org/api/http.html#http_http_createserver_options_requestlistener) options. ws es una biblioteca de servidor y cliente WebSocket de código abierto para Node.js. Un valor especialmente diseñado del encabezado "Sec-Websocket-Protocol" puede ser usado para ralentizar significativamente un servidor ws. • https://github.com/websockets/ws/commit/00c425ec77993773d823f018f64a5c44e17023ff https://github.com/websockets/ws/security/advisories/GHSA-6fc8-4gx4-v693 https://lists.apache.org/thread.html/rdfa7b6253c4d6271e31566ecd5f30b7ce1b8fb2c89d52b8c4e0f4e30%40%3Ccommits.tinkerpop.apache.org%3E https://security.netapp.com/advisory/ntap-20210706-0005 • CWE-400: Uncontrolled Resource Consumption •
