Description

phpMyFAQ has Weak Cryptography - SHA1 for Password Hashing

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

<img width="810" height="427" alt="image" src="https://github.com/user-attachments/assets/6499a008-3ece-4291-8296-f1d3303ba35c" />

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);

}

```

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. Rated impact: confidentiality low, integrity none, availability none.

  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Confidentiality impact: Low — limited, and the attacker does not choose what is affected.
  • Integrity impact: None.
  • Availability impact: None.
