At a glance
CVE-2015-10102 is a medium-severity URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the Freshdesk (official) WordPress plugin, affecting versions 1.7. 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; sites on affected versions should update now. Disclosed April 2023.
Vulnerability Overview
The Freshdesk (official) Plugin for WordPress is vulnerable to Open Redirect in versions up to, and including, 1.7. This is due to the application failing to properly verify user-supplied input from the `$redirect_url` value. This makes it possible for unauthenticated attackers to exploit this issue and redirect users to arbitrary web sites and conduct phishing attacks; other attacks are also possible.
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 Freshdesk (official) 1.7 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 Freshdesk (official) the fix is 1.8: builds 1.7 are affected, anything from 1.8 onward is not.
Remediation
Update to version 1.8, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Freshdesk (official): WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Freshdesk (official) 1.8 closes this, and updating the plugin is the step that ends it.
