Permissions, Privileges, and Access Controls
CMS Made Simple 184.108.40.206 does not check the permissions assigned to users in some situations, which allows remote authenticated users to perform some administrative actions, as demonstrated by (1) adding a user via a direct request to admin/adduser.php and (2) reading the admin log via an "admin/adminlog.php?page=1" request.
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.
