At a glance
This record tracks a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Image Slider WordPress plugin, affecting versions <= 1.1.119. 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 1.1.121; sites on affected versions should update now. Disclosed May 2022.
Vulnerability Overview
The plugin Image Slider is vulnerable to SQL Injection via the post parameter in the function ewic_duplicate_slider in versions up to, and including 1.1.119 due to insufficient sanitization before using it in an unprepared SQL query. This make it possible for subscribers 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 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 Image Slider <= 1.1.119 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 Image Slider the fix is 1.1.121: builds <= 1.1.119 are affected, anything from 1.1.121 onward is not.
Remediation
Update to version 1.1.121, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Image Slider: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Image Slider 1.1.121 closes this, and updating the plugin is the step that ends it.
