"The remote WordPress application has a plugin installed that is vulnerable to multiple vulnerabilities.");
  script_set_attribute(attribute:"description", value:
"The WordPress application running on the remote host has a version of the 'LearnPress' plugin that is prior to 3.2.6.8
and, thus, is affected by multiple vulnerabilities :

  - A SQL injection (SQLi) vulnerability exists in the _get_items method of the LP_Modal_Search_Items class
    due to improper validation of user-supplied input. An authenticated, remote attacker can exploit this to
    inject or manipulate SQL queries in the back-end database, resulting in the disclosure or manipulation of
    arbitrary data. (CVE-2020-6010)

  - A privilege escalation vulnerability exists in the learn_press_accept_become_a_teacher function due to the
    code not checking the permissions of the requesting user. An unauthenticated, remote attacker can exploit
    this, via /wpadmin/, to gain 'teacher' access to the application. (CVE-2020-11511)

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's
self-reported version number.");
