At a glance

CVE-2022-0411 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Asgaros Forum WordPress plugin, affecting versions < 2.0.0. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 2.0.0; sites on affected versions should update now. Disclosed January 2022, reported by Krzysztof Zając.

Vulnerability Overview

The Asgaros Forum WordPress plugin before 2.0.0 does not sanitise and escape the post_id parameter before using it in a SQL statement via a REST route of the plugin (accessible to any authenticated user), 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 Asgaros Forum < 2.0.0 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 Asgaros Forum the fix is 2.0.0: builds < 2.0.0 are affected, anything from 2.0.0 onward is not.

Remediation

Update to version 2.0.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Asgaros Forum: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Asgaros Forum 2.0.0 closes this, and updating the plugin is the step that ends it.
