At a glance
CVE-2021-25060 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Five Star Business Profile and Schema WordPress plugin, affecting versions <= 2.1.6. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). The issue is fixed in version 2.1.7; sites on affected versions should update now. Disclosed January 2022, reported by Krzysztof Zając.
Vulnerability Overview
The Five Star Business Profile and Schema WordPress plugin before 2.1.7 does not have any authorisation and CSRF in its bpfwp_welcome_add_contact_page and bpfwp_welcome_set_contact_information AJAX action, allowing any authenticated users, such as subscribers, to call them. Furthermore, due to the lack of sanitisation, it also lead to Stored Cross-Site Scripting issues
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Five Star Business Profile and Schema <= 2.1.6 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Five Star Business Profile and Schema the fix is 2.1.7: builds <= 2.1.6 are affected, anything from 2.1.7 onward is not.
Remediation
Update to version 2.1.7, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Five Star Business Profile and Schema: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Five Star Business Profile and Schema 2.1.7 closes this, and updating the plugin is the step that ends it.
