Overview

The OrdaSoft Joomla Gallery extension (v<6.2.7) contains an authenticated, privileged SQL injection that allows a core.manage user to read and write the database, including extracting user password hashes. This flaw arises from unsanitized form data being concatenated into SQL queries. It enables attackers with gallery‑management rights to compromise the entire site’s data integrity and confidentiality.

Description

Joomla Extension - OrdaSoft.com - Authenticated, Privileged SQL Injection in OrdaSoft Joomla Gallery extension for Joomla < 6.2.7 - The extensions saveGallery() passes form data through a hand-rolled parser into Joomla’s Input object, then reads it back with the ARRAY/ STRING filter types, neither of which sanitises SQL content. Values from category_names[], catOrderIds, and image-ordering fields were concatenated directly into SQL with no quoting or integer cast, giving an authenticated core.manage user (a permission scoped to managing one gallery component, not administrator-wide trust) full read/write access to the database, including UNION-based extraction of #__users password hashes.

Impact

Confidentiality is breached as attackers can retrieve user credentials and sensitive data. Integrity is compromised because the attacker can modify or delete database records. Availability is not directly affected, but the loss of data integrity can lead to service disruption. The primary impact is on site administrators and users whose accounts may be exposed.

Remediation

Apply the latest patch (v6.2.7 or newer) for the OrdaSoft Joomla Gallery extension. If an update is not immediately possible, restrict the core.manage role to only trusted users, disable the gallery extension, and implement input validation or parameterized queries in the extension code. Monitor database logs for anomalous queries and enforce least‑privilege access controls.

Risk context

The vulnerability is rated high severity with CVSS v3 score 7.2 and CVSS v4 score 8.6, indicating a significant risk. Immediate remediation is recommended to prevent potential credential theft and data tampering.
