Technical Analysis

CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Remediation

Update to version 4.1.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to 3CX Free Live Chat, Calls & Messaging: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: 3CX Free Live Chat, Calls & Messaging 4.1.0 closes this, and updating the plugin is the step that ends it.
