Description

All Craft CMS versions between 3.0.0 and 3.7.32 disclose password hashes of users who authenticate using their E-Mail address or username in Anti-CSRF-Tokens. Craft CMS uses a cookie called CRAFT_CSRF_TOKEN and a HTML hidden field called CRAFT_CSRF_TOKEN to avoid Cross Site Request Forgery attacks. The CRAFT_CSRF_TOKEN cookie discloses the password hash in without encoding it whereas the corresponding HTML hidden field discloses the users' password hash in a masked manner, which can be decoded by using public functions of the YII framework.

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

How to prevent it
  • Architecture and Design: Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.

CWE-522: Insufficiently Protected Credentials

The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.

How to prevent it
  • Architecture and Design: Use an appropriate security mechanism to protect the credentials.
  • Architecture and Design: Make appropriate use of cryptography to protect the credentials.
  • Implementation: Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
