At a glance

CVE-2019-13275 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WP Statistics WordPress plugin, affecting versions <= 12.6.6.1. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 12.6.7; sites on affected versions should update now. Disclosed July 2019, reported by Thomas Chauchefoin.

Vulnerability Overview

An issue was discovered in the VeronaLabs wp-statistics plugin before 12.6.7 for WordPress. The v1/hit endpoint of the API, when the non-default "use cache plugin" setting is enabled, is vulnerable to unauthenticated blind SQL Injection.

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, integrity, availability — full site compromise territory.

CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Reaching this weakness in WP Statistics <= 12.6.6.1 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 WP Statistics the fix is 12.6.7: builds <= 12.6.6.1 are affected, anything from 12.6.7 onward is not.

Remediation

Update to version 12.6.7, 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: WP Statistics 12.6.7 closes this, and updating the plugin is the step that ends it.
