At a glance
CVE-2022-0642 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the JivoChat Live Chat WordPress plugin, affecting versions <= 1.3.5.3. 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 1.3.5.4; sites on affected versions should update now. Disclosed May 2022, reported by Muhamad Hidayat.
Vulnerability Overview
The JivoChat Live Chat WordPress plugin before 1.3.5.4 does not properly check CSRF tokens on POST requests to the plugins admin page, and does not sanitise some parameters, leading to a stored Cross-Site Scripting vulnerability where an attacker can trick a logged in administrator to inject arbitrary javascript.
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 JivoChat Live Chat <= 1.3.5.3 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 JivoChat Live Chat the fix is 1.3.5.4: builds <= 1.3.5.3 are affected, anything from 1.3.5.4 onward is not.
Remediation
Update to version 1.3.5.4, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to JivoChat Live Chat: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: JivoChat Live Chat 1.3.5.4 closes this, and updating the plugin is the step that ends it.
