At a glance

CVE-2021-24774 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Check & Log Email WordPress plugin, affecting versions <= 1.0.2. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 1.0.3; sites on affected versions should update now. Disclosed September 2021, reported by bl4derunner.

Vulnerability Overview

The Check & Log Email WordPress plugin before 1.0.3 does not validate and escape the "order" and "orderby" GET parameters before using them in a SQL statement when viewing logs, leading to SQL injections issues

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')

Check & Log Email <= 1.0.2 carries this weakness at order, and reaching it takes a caller who can reach the endpoint. 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 Check & Log Email the fix is 1.0.3: builds <= 1.0.2 are affected, anything from 1.0.3 onward is not.

Remediation

Update to version 1.0.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Check & Log Email: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Check & Log Email 1.0.3 closes this, and updating the plugin is the step that ends it.
