At a glance
CVE-2023-52135 is a medium-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WS Form LITE WordPress plugin, affecting versions < 1.9.171. It carries a CVSS score of 6.6 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 1.9.171; sites on affected versions should update now. Disclosed December 2023, reported by Muhammad Daffa.
Vulnerability Overview
The WS Form LITE – Drag & Drop Contact Form Builder for WordPress plugin for WordPress is vulnerable to SQL Injection via an unknown parameter in all versions up to 1.9.171 (exclusive) 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, with administrator access and above, 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, 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 WS Form LITE < 1.9.171 takes an account at Administrator 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 WS Form LITE the fix is 1.9.171: builds < 1.9.171 are affected, anything from 1.9.171 onward is not.
Remediation
Update to version 1.9.171, or a newer patched version
How does WordSec protect against this?
An attacker needs Administrator 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: WS Form LITE 1.9.171 closes this, and updating the plugin is the step that ends it.
