Detailsinfo

A vulnerability classified as critical has been found in trainingbusinesspros Groundhogg Plugin up to 4.9. Affected is the function process_edit. The manipulation of the argument user with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.9 This is due to a missing ownership and capability check on the `user` parameter within the `process_edit()` function, which allows any authenticated user with the `edit_contacts` capability to reassign a contact record's linked WordPress user ID to any arbitrary account without requiring the `edit_users` or `promote_users` capabilities. This makes it possible for authenticated attackers, with sales_rep-level access and above, to escalate their privileges to administrator by linking a contact to an administrator's WordPress user ID, then creating a note containing the `{auto_login_link}` replacement tag to trigger generation of a valid auto-login permissions-key URL for the administrator-linked contact, and finally visiting that URL to authenticate as the targeted administrator. The auto-login URL is stored in the note content and is readable back by the attacker via the `view_notes` and `add_notes` capabilities that the sales_rep role holds by default.
