Vulnerability Overview

The Asgaros Forum WordPress plugin before 1.15.15 does not validate or escape the forum_id parameter before using it in a SQL statement when editing a forum, leading to an SQL injection issue

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 <= 1.15.14 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 1.15.15: builds <= 1.15.14 are affected, anything from 1.15.15 onward is not.

Remediation

Update to version 1.15.15, 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 1.15.15 closes this, and updating the plugin is the step that ends it.
