Synopsis

WordPress 4.0.x < 4.0.19 Multiple Vulnerabilities

Description

According to its self-reported version number, the detected WordPress application is affected by multiple vulnerabilities :

- A flaw in $wpdb->prepare() can create unsafe queries leading to potential SQL injection flaws with plugins and themes.

- Multiple cross-site scripting (XSS) vulnerabilities exists due to improper sanitization of user-supplied input. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session.

- Multiple path traversal vulnerabilities exist in the file unzipping code and customizer. A remote attacker may be able to read arbitrary files subject to the privileges under which the web server runs.

- An open redirect flaw exists on the user and term edit screens. A remote attacker can exploit this, by tricking a user into following a specially crafted link, to redirect a user to an arbitrary website.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update to WordPress version 4.0.19 or latest.
