Permissions, Privileges, and Access Controls
The Admin Control Panel in Rianxosencabos CMS 0.9 does not require administrator privileges, which allows remote authenticated users to (1) change a user's privileges, (2) delete a user account, or perform unspecified other administrative actions via vectors involving an admin lista action to the default URI, possibly related to useradmin.php.
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.
