Vulnerability Overview

The AJdG AdRotate plugin before 5.3 for WordPress allows SQL Injection.

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

Reaching this weakness in AdRotate Banner Manager <= 5.2 takes any authenticated account. 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 AdRotate Banner Manager the fix is 5.3: builds <= 5.2 are affected, anything from 5.3 onward is not.

Remediation

Update to version 5.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to AdRotate Banner Manager: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: AdRotate Banner Manager 5.3 closes this, and updating the plugin is the step that ends it.
