7.3- Upgrade drupal/core to this version or later
Description
Drupal 7.x before 7.3 allows remote attackers to bypass intended node_access restrictions via vectors related to a listing that shows nodes but lacks a JOIN clause for the node table.
Affected versions
Packagist
| Package | Vulnerable | Fixed in |
|---|---|---|
| drupal/core | >= 7.0, < 7.3 |
7.3 |
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.
drupal/core Packagist → 7.3
- composer
composer require drupal/core:^7.3
Weakness
CWE-284: Improper Access Control
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
How to prevent it
- Architecture and Design, Operation: Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- 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.
