Vulnerability from github – Published: 2025-06-23 22:41 – Updated: 2025-06-27 23:38

Summary

pbkdf2 returns predictable uninitialized/zero-filled memory for non-normalized or unimplemented algos

Details

Summary

This affects both: 1. Unsupported algos (e.g. sha3-256 / sha3-512 / sha512-256) 2. Supported but non-normalized algos (e.g. Sha256 / Sha512 / SHA1 / sha-1 / sha-256 / sha-512)

All of those work correctly in Node.js, but this polyfill silently returns highly predictable ouput

Under Node.js (only with pbkdf2/browser import, unlikely) / Bun (pbkdf2 top-level import is affected), the memory is not zero-filled but is uninitialized, as Buffer.allocUnsafe is used

Under browsers, it just returns zero-filled buffers (Which is also critical, those are completely unacceptable as kdf output and ruin security)

Were you affected?

The full list of arguments that were not affected were literal: * 'md5' * 'sha1' * 'sha224' * 'sha256' * 'sha384' * 'sha512' * 'rmd160' * 'ripemd160'

Any other arguments, e.g. representation variations of the above ones like 'SHA-1'/'sha-256'/'SHA512' or different algos like 'sha3-512'/'blake2b512', while supported on Node.js crypto module, returned predictable output on pbkdf2 (or crypto browser/bundlers polyfill)

Beware of packages re-exporting this under a different signature, like (abstract):

const crypto = require('crypto')
module.exports.deriveKey = (algo, pass, salt) => crypto.pbkdf2Sync(pass, salt, 2048, 64, algo)

In this case, the resulting deriveKey method is also affected (to the same extent / conditions as listed here).

Environments

This affects require('crypto') in polyfilled mode (e.g. from crypto-browserify, node-libs-browser, vite-plugin-node-polyfills, node-stdlib-browser, etc. -- basically everything that bundles/polfyills crypto

In bundled code (e.g. Webpack / Vite / whatever), this affects require('crypto') and require('pbkdf2')
On Node.js, this does not affect require('pbkdf2') (or require('crypto') obviously), but affects require('pbkdf2/browser')
On Bun, this does affect require('pbkdf2') and require('pbkdf2/browser') (and returns uninitialized memory, often zeros / sparse flipped bytes)

PoC

const node = require('crypto')
const polyfill = require('pbkdf2/browser')

const algos = [
  'sha3-512', 'sha3-256', 'SHA3-384',
  'Sha256', 'Sha512', 'sha512-256',
  'SHA1', 'sha-1',
  'blake2b512',
  'RMD160', 'RIPEMD-160', 'ripemd-160',
]
for (const algo of algos) {
  for (const { pbkdf2Sync } of [node, polyfill]) {
    const key = pbkdf2Sync('secret', 'salt', 100000, 64, algo)
    console.log(`${algo}: ${key.toString('hex')}`);
  }
}

Output (odd lines are Node.js, even is pbkdf2 module / polyfill):

Uninitialized memory

const { pbkdf2Sync } = require('pbkdf2/browser') // or just 'pbkdf2' on Bun will do this too

let prev
for (let i = 0; i < 100000; i++) {
  const key = pbkdf2Sync('secret', 'salt', 100000, 64, 'sha3-256')
  const hex = key.toString('hex')
  if (hex !== prev) console.log(hex);
  prev = hex
}

Affected versions

Seems to be since https://github.com/browserify/pbkdf2/commit/9699045c37a07f8319cfb8d44e2ff4252d7a7078

Impact

This is critical, browserifying code might silently generate zero-filled keys instead of proper ones, for code that was working on Node.js or in test environment

Just updating to a fixed version is not enough: if anyone was using pbkdf2 lib (e.g. via crypto-browserify or directly) on algos not from the literal string list (see "were you affected"), recheck where those keys went / how they were used, and take action accordingly

Note

Most likely, you receive this either through a subdep using pbkdf2 module directly (and then it is used), or through crypto-browserify (and the usage depends on whether you or any of your subdeps were calling pbkdf2/pbkdf2Sync methods from Node.js crypto inside your bundle)

When targeting non-Node.js, prever avoiding Node.js crypto polyfill at all, and use crypto.subtle and/or modern/audited cryptography primitives instead

Severity

9.1 (Critical)

\u0027salt\u0027, 100000, 64, \u0027sha3-256\u0027)\n  const hex = key.toString(\u0027hex\u0027)\n  if (hex !== prev) console.log(hex);\n  prev = hex\n}\n```\n\n### Affected versions\n\nSeems to be since https://github.com/browserify/pbkdf2/commit/9699045c37a07f8319cfb8d44e2ff4252d7a7078\n\n### Impact\n\nThis is critical, browserifying code might silently generate zero-filled keys instead of proper ones, for code that was working on Node.js or in test environment\n\nJust updating to a fixed version is not enough: if anyone was using `pbkdf2` lib (e.g. via `crypto-browserify` or directly) on algos not from the literal string list (see \"were you affected\"), recheck where those keys went / how they were used,  and take action accordingly\n\n### Note\n\nMost likely, you receive this either through a subdep using `pbkdf2` module directly (and then it is used), or through `crypto-browserify` (and the usage depends on whether you or any of your subdeps were calling `pbkdf2/pbkdf2Sync` methods from Node.js crypto inside your bundle)\n\nWhen targeting non-Node.js, prever avoiding Node.js crypto polyfill at all, and use `crypto.subtle` and/or modern/audited cryptography primitives instead",

Possible Mitigations

Установка обновлений из доверенных источников. В связи со сложившейся обстановкой и введенными санкциями против Российской Федерации рекомендуется устанавливать обновления программного обеспечения только после оценки всех сопутствующих рисков. Компенсирующие меры: - использование средств межсетевого экранирования для ограничения возможности удалённого доступа к уязвимому программному обеспечению; - использование систем обнаружения и предотвращения вторжений для обнаружения (выявления, регистрации) и реагирования на попытки эксплуатации уязвимостей; - ограничение доступа к уязвимому программному обеспечению из внешних сетей (Интернет). Использование рекомендаций: Для Node.js: https://github.com/browserify/pbkdf2/commit/9699045c37a07f8319cfb8d44e2ff4252d7a7078 https://github.com/browserify/pbkdf2/commit/e3102a8cd4830a3ac85cd0dd011cc002fdde33bb Для РедОС: http://repo.red-soft.ru/redos/7.3c/x86_64/updates/

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
