WordPress < 4.8.2 Multiple Vulnerabilities
critical Nessus Plugin ID 103358
Language:
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 prior to 4.8.2.It is, therefore, 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 Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to WordPress version 4.8.2 or later.See Also
