Permissions, Privileges, and Access Controls
The Accounts Preferences implementation in Apple Mac OS X 10.6 before 10.6.3, when a network account server is used, does not support Login Window access control that is based solely on group membership, which allows attackers to bypass intended access restrictions by entering login credentials.
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.
