At a glance

CVE-2015-1055 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Photo Gallery by 10Web WordPress plugin, affecting versions < 1.2.8. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.2.8; sites on affected versions should update now. Disclosed January 2015, reported by Brandon Perry.

Vulnerability Overview

SQL injection vulnerability in the Photo Gallery plugin 1.2.7 for WordPress allows remote attackers to execute arbitrary SQL commands via the order_by parameter in a GalleryBox action to wp-admin/admin-ajax.php.

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')

Reaching this weakness in Photo Gallery by 10Web < 1.2.8 takes no account at all. 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 Photo Gallery by 10Web the fix is 1.2.8: builds < 1.2.8 are affected, anything from 1.2.8 onward is not.

Remediation

Update to version 1.2.8, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Photo Gallery by 10Web 1.2.8 closes this, and updating the plugin is the step that ends it.
