Vulnerability Overview

The Ad Invalid Click Protector (AICP) WordPress plugin before 1.2.6 is affected by a SQL Injection in the id parameter of the delete action.

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 Ad Invalid Click Protector (AICP) < 1.2.6 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 Ad Invalid Click Protector (AICP) the fix is 1.2.6: builds < 1.2.6 are affected, anything from 1.2.6 onward is not.

Remediation

Update to version 1.2.6, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Ad Invalid Click Protector (AICP): WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Ad Invalid Click Protector (AICP) 1.2.6 closes this, and updating the plugin is the step that ends it.
