At a glance
CVE-2018-6357 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Social Media Widget by Acurax WordPress plugin, affecting versions < 3.2.6. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.2.6; sites on affected versions should update now. Disclosed January 2018, reported by Panagiotis Vagenas.
Vulnerability Overview
The acx_asmw_saveorder_callback function in function.php in the acurax-social-media-widget plugin before 3.2.6 for WordPress has CSRF via the recordsArray parameter to wp-admin/admin-ajax.php, with resultant social_widget_icon_array_order XSS.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Social Media Widget by Acurax < 3.2.6 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Social Media Widget by Acurax the fix is 3.2.6: builds < 3.2.6 are affected, anything from 3.2.6 onward is not.
Remediation
Update to version 3.2.6, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Social Media Widget by Acurax: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Social Media Widget by Acurax 3.2.6 closes this, and updating the plugin is the step that ends it.
