EUVDB-ID: #VU19209

Risk: Low

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: N/A

CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to the lack of CSRF and authorisation checks in the settings page, as well as "ajax_enable_ssl()", "ajax_scan()" AJAX methods. A remote attacker can trick the victim to visit a specially crafted web page and perform settings change on the affected system.

This vulnerability also allows a call of the AJAX methods by a low privileged user and arbitrary site options update due to the way the update_option() and update_site_option() are used in the admin() and admin_network() functions.

Mitigation

Install updates from vendor's website.
