CVE-2022-3768
At a glance
CVE-2022-3768 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WPSmartContracts WordPress plugin, affecting versions <= 1.3.11. 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 at Author level or above. The issue is fixed in version 1.3.12; sites on affected versions should update now. Disclosed November 2022, reported by Kunal Sharma.
Vulnerability Overview
The WPSmartContracts plugin for WordPress is vulnerable to generic SQL Injection via an unknown parameter in versions up to, and including, 1.3.11 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for author-level 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 WPSmartContracts <= 1.3.11 takes an account at Author level or above. 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 WPSmartContracts the fix is 1.3.12: builds <= 1.3.11 are affected, anything from 1.3.12 onward is not.
Remediation
Update to version 1.3.12, or a newer patched version
How does WordSec protect against this?
An attacker needs Author access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WPSmartContracts 1.3.12 closes this, and updating the plugin is the step that ends it.
