The issue is fixed in version 2.2.4; sites on affected versions should update now. Disclosed June 2022, reported by Daniel Ruf.
Vulnerability Overview
The Social Share Buttons by Supsystic WordPress plugin before 2.2.4 does not perform CSRF checks in it's ajax endpoints and admin pages, allowing an attacker to trick any logged in user to manipulate or change the plugin settings, as well as create, delete and rename projects and networks.
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 Share Buttons by Supsystic <= 2.2.3 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 Share Buttons by Supsystic the fix is 2.2.4: builds <= 2.2.3 are affected, anything from 2.2.4 onward is not.
Remediation
Update to version 2.2.4, or a newer patched version
How does WordSec protect against this?
