Permissions, Privileges, and Access Controls


Severity Medium
Score 6.4/10


The hook_node_access function in the revisioning module 7.x-1.x before 7.x-1.3 for Drupal checks the permissions of the current user even when it is called to check permissions of other users, which allows remote attackers to bypass intended access restrictions, as demonstrated when using the XML sitemap module to obtain sensitive information about unpublished content.

CWE-264 - Permissions Privileges and Access Controls

CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
