Vulnerability Overview

An issue was discovered in the Huge-IT gallery-images plugin before 1.9.0 for WordPress. The headers Client-Ip and X-Forwarded-For are prone to unauthenticated SQL injection. The affected file is gallery-images.php. The affected function is huge_it_image_gallery_ajax_callback().

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 privileges on the target site, 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')

Image Gallery - Responsive Photo Gallery <= 1.8.9 carries this weakness at huge_it_image_gallery_ajax_callback(), and reaching it 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 Image Gallery - Responsive Photo Gallery the fix is 1.9.0: builds <= 1.8.9 are affected, anything from 1.9.0 onward is not.

Remediation

Update to version 1.9.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Image Gallery - Responsive Photo Gallery: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Image Gallery - Responsive Photo Gallery 1.9.0 closes this, and updating the plugin is the step that ends it.
