At a glance

CVE-2019-15773 is a medium-severity URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the Travel Management WordPress plugin, affecting versions <= 1.6.1. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.7; sites on affected versions should update now. Disclosed August 2019, reported by Jerome Bruandet.

Vulnerability Overview

The nd-travel plugin before 1.7 for WordPress has a nopriv_ AJAX action that allows modification of the siteurl setting.

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 Travel Management <= 1.6.1 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 Travel Management the fix is 1.7: builds <= 1.6.1 are affected, anything from 1.7 onward is not.

Remediation

Update to version 1.7, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Travel Management: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Travel Management 1.7 closes this, and updating the plugin is the step that ends it.
