Weak Password Recovery Mechanism for Forgotten Password
The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.
Weak password recovery mechanisms can be exploited to take over user accounts. Common issues include predictable reset tokens, security questions with easily guessable answers, or lack of verification.
Jak naprawić tę podatność
Strategie zapobiegania dla Weak Password Recovery oparte na 3 regułach detekcji Shoulder.
Use crypto/rand with 32+ bytes of entropy for password reset tokens
- func generateResetToken() string { - return fmt.Sprintf("%d", time.Now().Unix()) + import ( + "crypto/rand" + "encoding/hex" + ) + + func generateResetToken() (string, error) { + b := make([]byte, 32) + if _, err := rand.Read(b); err != nil { + return "", err + } + return hex.EncodeToString(b), nil }
Use crypto.randomBytes() instead of Math.random() for security tokens
- user.resetToken = Math.random().toString(36); + const crypto = require('crypto'); + user.resetToken = crypto.randomBytes(32).toString('hex'); await user.save();
Use the secrets module for cryptographically secure token generation
- import random - - def create_reset_token(): - chars = 'abcdef0123456789' - reset_token = ''.join(random.choice(chars) for _ in range(32)) - return reset_token + import secrets + + def create_reset_token(): + return secrets.token_urlsafe(32)
