CVSS: 7.9EPSS: 0%CPEs: 1EXPL: 0CVE-2024-21896 – nodejs: path traversal by monkey-patching buffer internals
https://notcve.org/view.php?id=CVE-2024-21896
20 Feb 2024 — The permission model protects itself against path traversal attacks by calling path.resolve() on any paths given by the user. If the path is to be treated as a Buffer, the implementation uses Buffer.from() to obtain a Buffer from the result of path.resolve(). By monkey-patching Buffer internals, namely, Buffer.prototype.utf8Write, the application can modify the result of path.resolve(), which leads to a path traversal vulnerability.

https://notcve.org/view.php?id=CVE-2024-21890
20 Feb 2024 — The Node.js Permission Model does not clarify in the documentation that wildcards should be only used as the last character of a file path. For example: ``` --allow-fs-read=/home/node/.ssh/*.pub ``` will ignore `pub` and give access to everything after `.ssh/`. This misleading documentation affects all users using the experimental permission model in Node.js 20 and Node.js 21. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

20 Feb 2024 — Node.js depends on multiple built-in utility functions to normalize paths provided to node:fs functions, which can be overwitten with user-defined implementations leading to filesystem permission model bypass through path traversal attack.

CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2024-22019 – nodejs: reading unprocessed HTTP request with unbounded chunk extension allows DoS attacks
https://notcve.org/view.php?id=CVE-2024-22019
20 Feb 2024 — 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.

https://notcve.org/view.php?id=CVE-2024-21892
20 Feb 2024 — 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. En Linux, Node.js ignora ciertas variables de entorno si p... • http://www.openwall.com/lists/oss-security/2024/03/11/1 • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-269: Improper Privilege Management •

28 Dec 2023 — Maliciously crafted export names in an imported WebAssembly module can inject JavaScript code. The injected code may be able to access data and functions that the WebAssembly module itself does not have access to, similar to as if the WebAssembly module was a JavaScript module. This vulnerability affects users of any active release line of Node.js. The vulnerable feature is only available if Node.js is started with the `--experimental-wasm-modules` command line option.
