Synopsis

The remote WordPress application has a plugin installed that is vulnerable to multiple vulnerabilities.

Description

The WordPress application running on the remote host has a version of the 'Email Subscribers & Newsletters' plugin that is affected by multiple vulnerabilities.

- A cross-site request forgery (CSRF) vulnerability exists in the send_test_email component. An unauthenticated, remote attacker can exploit this, by tricking a user into visiting a specially crafted web page, to send forged emails. (CVE-2020-5767)

- A blind SQL injection vulnerability exists in the es_newsletters_settings_callback component due to improper sanitization of user supplied input. An authenticated, remote attacker can exploit this issue via a specially crafted request to disclose potentially sensitive information. (CVE-2020-5768)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the 'Email Subscribers & Newsletters' plugin to version 4.5.1 or later.
