The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 77a6f1c9-d7d2-11ee-bb12-001b217b3468 advisory.

  - 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. (CVE-2024-21890)

  - 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. Please note that at the time this CVE was issued, the permission model     is an experimental feature of Node.js. (CVE-2024-21891)

  - 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. (CVE-2024-21892)

  - 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. Please note that at the time this CVE was issued, the permission model is an     experimental feature of Node.js. (CVE-2024-21896)

  - 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. (CVE-2024-22019)

  - A vulnerability in the privateDecrypt() API of the crypto library, allowed a covert timing side-channel     during PKCS#1 v1.5 padding error handling. The vulnerability revealed significant timing differences in     decryption for valid and invalid ciphertexts. This poses a serious threat as attackers could remotely     exploit the vulnerability to decrypt captured RSA ciphertexts or forge signatures, especially in scenarios     involving API endpoints processing Json Web Encryption messages. Impacts: Thank you, to hkario for     reporting this vulnerability and thank you Michael Dawson for fixing it. (CVE-2023-46809)

  - setuid() does not affect libuv's internal io_uring operations if initialized before the call to setuid().
    This allows the process to perform privileged operations despite presumably having dropped such privileges     through a call to setuid(). Impacts: Thank you, to valette for reporting this vulnerability and thank you     Tobias Nieen for fixing it. (CVE-2024-22017)

  -  Denial of Service by resource exhaustion in fetch() brotli decoding. (CVE-2024-22025)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
