At a glance

This record tracks a medium-severity URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the Photo Gallery by 10Web WordPress plugin, affecting versions <= 1.8.7. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.8.8; sites on affected versions should update now. Disclosed November 2022.

Vulnerability Overview

The Photo Gallery by 10Web plugin for WordPress is vulnerable to open redirect in versions up to 1.8.7. This is due to insufficient validation of the curr_url ($current_url) request parameter when a user accesses a link with an invalid share link. This would make it possible for an attacker to redirect a victim to a potentially malicious site, granted they could trick the victim into performing an action such as clicking on a link. The patches in 1.8.1, 1.8.3, 1.8.7 are incomplete and can be bypassed.

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.

CWE-601: URL Redirection to Untrusted Site ('Open Redirect')

Reaching this weakness in Photo Gallery by 10Web <= 1.8.7 takes a caller who can reach the endpoint. An open redirect is a page that takes a destination from the request and sends the browser there without checking that the destination belongs to the site.

A link that starts on a trusted domain finishes on an attacker's, which is what makes phishing and consent-screen abuse credible to the person clicking it. For Photo Gallery by 10Web the fix is 1.8.8: builds <= 1.8.7 are affected, anything from 1.8.8 onward is not.

Remediation

Update to version 1.8.8, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Photo Gallery by 10Web: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Photo Gallery by 10Web 1.8.8 closes this, and updating the plugin is the step that ends it.
