Permissions, Privileges, and Access Controls
uPortal before 22.214.171.124 does not properly check the MANAGE permissions, which allows remote authenticated users to manage arbitrary portlets by leveraging the SUBSCRIBE permission for the portlet-admin portlet.
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.
