Synopsis

A PHP application running on the remote web server is affected by multiple vulnerabilities.

Description

According to its self-reported version number, the WordPress application running on the remote web server is affected by multiple vulnerabilities:

- A cross-site request forgery (XSRF) vulnerability exists in the comment form due to improper validation. A remote attacker can exploit this by tricking a user into visiting a specially crafted web page, allowing the attacker to create comments on the administrator's behalf. (CVE-2019-9787)

- A cross-site scripting (XSS) vulnerability exists due to improper validation of user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.

Solution

Upgrade to WordPress version 5.1.1 or later.
