Weak MD5 Password Hashing in Redeight CMS 1.0

Executive Summary

Redeight CMS version 1.0 stores user passwords using the MD5 hashing algorithm without adding a salt.

MD5 is a cryptographically broken algorithm, and without salting, the password hashes are vulnerable to being reversed by attackers using rainbow tables.

This means that if an attacker obtains the password hashes, they can easily recover the original plaintext passwords.

Detection Guidance

This vulnerability involves the use of the MD5 algorithm without salting to store user passwords in Redeight CMS version 1.0. To detect it on your system, you can check the password storage mechanism by inspecting the database where user credentials are stored.

Specifically, you can query the database to retrieve password hashes and verify if they are stored as unsalted MD5 hashes.

• Use SQL commands to extract password hashes, for example: SELECT user_password FROM users;
• Check if the hashes are 32-character hexadecimal strings typical of MD5 hashes.
• Compare the hashes against known MD5 rainbow tables or use tools like 'hashcat' or 'john the ripper' to test if they can be reversed easily.

Impact Analysis

If an attacker gains access to the password hashes stored by Redeight CMS, they can quickly reverse them to obtain users' plaintext passwords.

This can lead to unauthorized access to user accounts, potential data breaches, and compromise of sensitive information.

Compliance Impact

The vulnerability involves the use of the MD5 algorithm without salting to store user passwords, which is cryptographically broken and allows attackers to easily reverse password hashes. This exposure of plaintext credentials can lead to unauthorized access to personal data.

Such a weakness in password storage can negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require adequate protection of personal and sensitive data to prevent unauthorized access and data breaches.

Mitigation Strategies

To mitigate this vulnerability, you should immediately stop using MD5 without salting for password storage.

Implement a stronger password hashing algorithm such as bcrypt, Argon2, or PBKDF2 with proper salting to securely store user passwords.

Additionally, consider forcing a password reset for all users to ensure that any previously compromised hashes are no longer valid.

If an update or patch is available for Redeight CMS that addresses this issue, apply it as soon as possible.
