At a glance
CVE-2021-24457 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Portfolio Responsive Gallery WordPress plugin, affecting versions <= 1.1.7. 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 1.1.8; sites on affected versions should update now. Disclosed June 2021, reported by To Quang Duong.
Vulnerability Overview
The get_portfolios() and get_portfolio_attributes() functions in the class-portfolio-responsive-gallery-list-table.php and class-portfolio-responsive-gallery-attributes-list-table.php files of the Portfolio Responsive Gallery WordPress plugin before 1.1.8 did not use whitelist or validate the orderby parameter before using it in SQL statements passed to the get_results() DB calls, leading to SQL injection issues in the admin dashboard
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')
Portfolio Responsive Gallery <= 1.1.7 carries this weakness at get_portfolios(), 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 Portfolio Responsive Gallery the fix is 1.1.8: builds <= 1.1.7 are affected, anything from 1.1.8 onward is not.
Remediation
Update to version 1.1.8, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Portfolio Responsive Gallery: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Portfolio Responsive Gallery 1.1.8 closes this, and updating the plugin is the step that ends it.
