Drupal Nodes with Misconfigured Access Controls
Description:
The way Drupal is built is made for flexibility, all content are stored separately in a new node. Including a page, an article, topic or blog entry. Nodes can contain sensitive data and if permissions are not enforced, they can leak private data to unauthorized users.
Testing:
Each node gets an individual ID assigned, in a black-box scenario where you have limited access to amount of nodes available. It is recommended to check thousands of IDs by making use of targeted bruteforcing
To do so, replace the positional {ID} parameter and replace it with a numerical value (for example: 1):
Keep incrementing the ID until you come an existing node ID and examine the response manually.
Remediation:
Introduce effective access controls for each node.
Potential Impact:
Drupal Nodes can expose a variety of potential sensitive data, for example private data from clients or other users as well as internal pages only meant to be accessed by site administrators.
