WordPress Ultimate Member Plugin Other Vulnerability - CVE-2022-3384
The Ultimate Member plugin for WordPress is vulnerable to Remote Code Execution in versions up to and including 2.5.0 via the populate_dropdown_options function that accepts user supplied input and passes it through call_user_func(). This is restricted to non-parameter PHP functions like phpinfo() since user supplied parameters are not passed through the function. This makes it possible for authenticated attackers with administrative privileges to execute code on the server.
