At a glance

This record tracks a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Image Gallery - Responsive Photo Gallery WordPress plugin, affecting versions <= 1.9.57. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.9.58; sites on affected versions should update now. Disclosed May 2016.

Vulnerability Overview

The Image Gallery - Responsive Photo Gallery plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.9.57. This is due to missing or incorrect nonce validation on the editgallery() function. This makes it possible for unauthenticated attackers to modify image galleries via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-352: Cross-Site Request Forgery (CSRF)

Image Gallery - Responsive Photo Gallery <= 1.9.57 carries this weakness at editgallery(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Image Gallery - Responsive Photo Gallery the fix is 1.9.58: builds <= 1.9.57 are affected, anything from 1.9.58 onward is not.

Remediation

Update to version 1.9.58, 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 1.9.58 closes this, and updating the plugin is the step that ends it.
