Vulnerability Overview

A SQL injection vulnerability exists in the FolioVision FV Flowplayer Video Player plugin before 7.3.19.727 for WordPress. Successful exploitation of this vulnerability would allow a remote attacker to execute arbitrary SQL commands on the affected system.

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, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Reaching this weakness in FV Flowplayer Video Player <= 7.3.18.727 takes a caller who can reach the endpoint. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For FV Flowplayer Video Player the fix is 7.3.19.727: builds <= 7.3.18.727 are affected, anything from 7.3.19.727 onward is not.

Remediation

Update to version 7.3.19.727, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to FV Flowplayer Video Player: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: FV Flowplayer Video Player 7.3.19.727 closes this, and updating the plugin is the step that ends it.
