At a glance
CVE-2024-10570 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Security Plugin, Firewall & Malware Scanner with Auto Removal WordPress plugin, affecting versions <= 2.145. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 2.145.1; sites on affected versions should update now. Disclosed November 2024, reported by mikemyers.
Vulnerability Overview
The Security & Malware scan by CleanTalk plugin for WordPress is vulnerable to unauthorized SQL Injection due to an authorization bypass via reverse DNS spoofing on the checkWithoutToken function in all versions up to, and including, 2.145, as well as insufficient input sanitization and validation. This makes it possible for unauthenticated 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 privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.
CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Reaching this weakness in Security Plugin, Firewall & Malware Scanner with Auto Removal <= 2.145 takes no account at all. 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 Security Plugin, Firewall & Malware Scanner with Auto Removal the fix is 2.145.1: builds <= 2.145 are affected, anything from 2.145.1 onward is not.
Remediation
Update to version 2.145.1, or a newer patched version
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Security Plugin, Firewall & Malware Scanner with Auto Removal 2.145.1 closes this, and updating the plugin is the step that ends it.
