At a glance

CVE-2022-0267 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the AdRotate Banner Manager WordPress plugin, affecting versions <= 5.8.17. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 5.8.22; sites on affected versions should update now. Disclosed February 2022, reported by ZhongFu Su.

Vulnerability Overview

The AdRotate WordPress plugin before 5.8.22 does not sanitise and escape the adrotate_action before using it in a SQL statement via the adrotate_request_action function available to admins, leading to a 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 <= 5.8.17 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 AdRotate Banner Manager the fix is 5.8.22: builds <= 5.8.17 are affected, anything from 5.8.22 onward is not.

Remediation

Update to version 5.8.22, 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 5.8.22 closes this, and updating the plugin is the step that ends it.
