Summary
phpMyFAQ has Weak Cryptography - SHA1 for Password Hashing
Details

Summary

Attachment passwords are hashed using SHA-1, a cryptographically broken algorithm. SHA-1 has been vulnerable to collision attacks since 2017 (SHAttered).

Details

Affected File : phpmyfaq/src/phpMyFAQ/Attachment/AbstractAttachment.php

image

Impact

  • An attacker can generate SHA-1 collisions to bypass attachment protection
  • Risk of password cracking if database is compromised
  • Estimated cracking time: < 1 minute for standard attachment

Solution

Use bcrypt:

public function setPassword(string $password): void
{
    $this->passwordHash = password_hash($password, PASSWORD_BCRYPT);
}

public function verifyPassword(string $plainPassword): bool
{
    return password_verify($plainPassword, $this->passwordHash);
}
Severity
2.7 (Low)
