Nodejs: >> Node.js >> 20.3.1 Security Vulnerabilities
A vulnerability has been identified in Node.js, specifically affecting the handling of drive names in the Windows environment. Certain Node.js functions do not treat drive names as special on Windows. As a result, although Node.js assumes a relative path, it actually refers to the root directory.
On Windows, a path that does not start with the file separator is treated as relative to the current directory.
This vulnerability affects Windows users of `path.join` API.

A command inject vulnerability allows an attacker to perform command injection on Windows applications that indirectly depend on the CreateProcess function when the specific conditions are satisfied.

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.

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.
This vulnerability affects all users using the experimental permission model in Node.js 20 and Node.js 21.

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.

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.
This vulnerability affects all users using the experimental permission model in Node.js 20 and Node.js 21.

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.

When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the application can intercept the operation and return a forged checksum to the node's policy implementation, thus effectively disabling the integrity check.
Impacts:
This vulnerability affects all users using the experimental policy mechanism in all active release lines: 18.x and, 20.x.
Please note that at the time this CVE was issued, the policy mechanism is an experimental feature of Node.js.

A previously disclosed vulnerability (CVE-2023-30584) was patched insufficiently in commit 205f1e6. The new path traversal vulnerability arises because the implementation does not protect itself against the application overwriting built-in utility functions with user-defined implementations.
Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

Various `node:fs` functions allow specifying paths as either strings or `Uint8Array` objects. In Node.js environments, the `Buffer` class extends the `Uint8Array` class. Node.js prevents path traversal through strings (see CVE-2023-30584) and `Buffer` objects (see CVE-2023-32004), but not through non-`Buffer` `Uint8Array` objects.
This is distinct from CVE-2023-32004 which only referred to `Buffer` objects. However, the vulnerability follows the same pattern using `Uint8Array` instead of `Buffer`.
Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.
