-------- DESCRIPTION ---------------------------------------------------------
The Services module enables you to expose an API to third party systems using REST, XML-RPC or other protocols.
.... User update access bypass vulnerability
An authenticated user is able to assign additional roles to themselves, which means they can escalate their privileges by assigning an administrative role.
This vulnerability is mitigated by the fact that the user must be able to log in on the site, the update operation on the user resource configuration must be enabled, and a site must have an role with more permissions than the authenticated user.
.... Comment access bypass vulnerability
As an authenticated user an attacker with the permission to post comments is able to update other users' comments.
This vulnerability is mitigated by the fact that the update operation on the comment resource configuration must be enabled.
