Frontend Admin by DynamiApps vulnerabilities

The Frontend Admin by DynamiApps plugin for WordPress up to version 3.29.9 contains a privilege escalation vulnerability. It stems from a flawed condition in the `ActionUser::conditions_logic()` function that skips the authorization check when the user ID is a string, allowing an attacker to escalate privileges to administrator.

The Frontend Admin by DynamiApps plugin versions up to 3.29.10 contain an Unauthenticated Privilege Escalation vulnerability. A remote unauthenticated attacker can escalate privileges in the system.

The Frontend Admin by DynamiApps WordPress plugin before 3.29.11 does not perform a capability check on one of its AJAX actions, allowing any authenticated user, such as a subscriber, to delete arbitrary membership plans.

Cross Site Scripting (XSS) vulnerability in Frontend Admin by DynamiApps in versions up to 3.29.10. A user with Contributor role can inject malicious script.

The Frontend Admin by DynamiApps plugin for WordPress, in all versions up to and including 3.29.9, is vulnerable to authorization bypass. Authenticated attackers with subscriber-level and above permissions can reset the password of any user, including administrators, leading to full account takeover and complete site compromise.

Broken Access Control vulnerability in Frontend Admin by DynamiApps plugin up to version 3.29.10, allowing a subscriber user to access administrative functions without authorization.

The Frontend Admin by DynamiApps WordPress plugin before version 3.29.9 decodes HTML entities in a submitted form field value after sanitizing it, which restores HTML tags that the sanitizer had neutralized. A double-encoded payload submitted by an unauthenticated visitor is therefore stored as a live tag and later output without escaping on the plugin's front-end display surfaces, resulting in stored cross-site scripting that executes in the browser of any user, including an administrator, who views a page displaying the submitted value.

The Frontend Admin by DynamiApps WordPress plugin before 3.29.7 does not perform capability checks on its taxonomy term creation, modification, and deletion operations. Authenticated users with low privileges (such as Subscribers) can create, rename, and delete arbitrary taxonomy terms.

The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to generic SQL Injection via the 'order' parameter in all versions up to, and including, 3.28.28 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires that the attacker also supply a valid 'orderby' parameter in the same request, as this is necessary to reach the vulnerable code path that processes and concatenates the 'order' value into the SQL query.
