Description
Laravel before 5.5.10 mishandles the remember_me token verification process because DatabaseUserProvider does not have constant-time token comparison.
Affected versions
Packagist
| Package | Vulnerable | Fixed in |
|---|---|---|
| illuminate/auth | < 5.5.10 |
5.5.10 |
| laravel/framework | < 5.5.10 |
5.5.10 |
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.
illuminate/auth Packagist → 5.5.10
- composer
composer require illuminate/auth:^5.5.10
laravel/framework Packagist → 5.5.10
- composer
composer require laravel/framework:^5.5.10

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.
