Vulnerability Overview

The Live Streaming - Broadcast Live Video Plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 5.5.15. This allows unauthenticated attackers to execute code on the server.

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 interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-20: Improper Input Validation

Reaching this weakness in Broadcast Live Video <= 5.5.15 takes no account at all. Improper input validation means the application accepts input without confirming it has the form, type or range the code downstream assumes.

The concrete impact depends on where the unvalidated value lands, which is why records in this class range from cosmetic bugs to full compromise. For Broadcast Live Video the fix is 5.5.16: builds <= 5.5.15 are affected, anything from 5.5.16 onward is not.

Remediation

Update to version 5.5.16, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Broadcast Live Video 5.5.16 closes this, and updating the plugin is the step that ends it.
