Manifest, Cryptographic Weakness, CVE-XXXX-XXXX (Critical)

By /

How the CVE Works:

The vulnerability in Manifest arises from its use of the SHA3 hashing algorithm without incorporating a unique salt for each user’s password. This deterministic approach means that identical passwords will produce identical hashes. When an attacker gains access to the database, they can easily identify patterns in the hashes, making it simpler to crack passwords using precomputed hash databases like Rainbow Tables or brute-force attacks. The absence of a salt significantly reduces the security of the hashing process, exposing user credentials to a higher risk of compromise.

DailyCVE Form:

Platform: Manifest
Version: All versions
Vulnerability: Weak password hashing
Severity: Critical
Date: YYYY-MM-DD

What Undercode Say:

Exploitation:

  1. Database Access: Attackers gain access to the password hash database.
  2. Hash Comparison: Identical hashes for the same password are identified.
  3. Rainbow Tables: Precomputed hash databases are used to reverse-engineer passwords.
  4. Brute-Force Attacks: Offline attacks are performed to crack weak passwords.

Protection:

  1. Use Salts: Implement unique salts for each user’s password.
  2. Upgrade Hashing: Replace SHA3 with bcrypt, scrypt, or Argon2.

3. Password Policies: Enforce strong password requirements.

  1. Regular Audits: Conduct security audits to identify vulnerabilities.

Commands:

1. Generate a unique salt:

import os 
salt = os.urandom(16)

2. Hash password with bcrypt:

import bcrypt 
hashed_password = bcrypt.hashpw(password.encode('utf-8'), bcrypt.gensalt())

3. Verify password:

bcrypt.checkpw(password.encode('utf-8'), hashed_password)

Code Snippets:

1. Salting Implementation:

const crypto = require('crypto'); 
const salt = crypto.randomBytes(16).toString('hex'); 
const hash = crypto.createHash('sha3-256').update(password + salt).digest('hex');

2. Bcrypt Implementation:

const bcrypt = require('bcrypt'); 
const saltRounds = 10; 
bcrypt.hash(password, saltRounds, function(err, hash) { 
// Store hash in database 
});

  1. Affected Users: All users with accounts on the platform.
  2. Mitigation Urgency: Immediate action required to prevent exploitation.
  3. Common Targets: Systems with weak password policies and no salting.
