At a glance

CVE-2021-24132 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Slider by 10Web WordPress plugin, affecting versions <= 1.2.35. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 1.2.36; sites on affected versions should update now. Disclosed September 2020, reported by Nguyen Anh Tien.

Vulnerability Overview

The Slider by 10Web WordPress plugin, versions before 1.2.36, in the bulk_action, export_full and save_slider_db functionalities of the plugin were vulnerable, allowing a high privileged user (Admin), or medium one such as Contributor+ (if "Role Options" is turn on for other users) to perform a SQL Injection attacks.

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 Slider by 10Web <= 1.2.35 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 Slider by 10Web the fix is 1.2.36: builds <= 1.2.35 are affected, anything from 1.2.36 onward is not.

Remediation

Update to version 1.2.36, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Slider by 10Web: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Slider by 10Web 1.2.36 closes this, and updating the plugin is the step that ends it.
