At a glance
This record tracks a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the User Profile Builder WordPress plugin, affecting versions < 3.3.3. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account. The issue is fixed in version 3.3.3; sites on affected versions should update now. Disclosed December 2020, reported by Lenon Leite.
Vulnerability Overview
The Profile Builder/Profile Builder Pro plugins for WordPress is vulnerable to blind SQL Injection via multiple parameters in versions up to, and including, 3.3.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
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 interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Reaching this weakness in User Profile Builder < 3.3.3 takes any authenticated account. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.
A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For User Profile Builder the fix is 3.3.3: builds < 3.3.3 are affected, anything from 3.3.3 onward is not.
Remediation
Update to version 3.3.3, or a newer patched version
How WordSec helps
The attempt arrives as an ordinary request to User Profile Builder: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: User Profile Builder 3.3.3 closes this, and updating the plugin is the step that ends it.
