According to its self-reported version, the Ultimate Form Builder Lite Plugin for WordPress running on the remote web server is prior to 1.3.7. It is therefore, affected by a SQL Injection vulnerability, resulting in PHP Object Injection exploitation vectors.
With a specially crafted request, a remote, authenticated attacker can inject PHP objects and potentially execute arbitrary code.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
