At a glance

CVE-2021-24139 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Photo Gallery by 10Web WordPress plugin, affecting versions < 1.5.55. 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 1.5.55; sites on affected versions should update now. Disclosed May 2020, reported by Nguyen Anh Tien.

Vulnerability Overview

Unvalidated input in the Photo Gallery (10Web Photo Gallery) WordPress plugin, versions before 1.5.55, leads to SQL injection via the frontend/models/model.php bwg_search_x parameter.

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 Photo Gallery by 10Web < 1.5.55 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 Photo Gallery by 10Web the fix is 1.5.55: builds < 1.5.55 are affected, anything from 1.5.55 onward is not.

Remediation

Update to version 1.5.55, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Photo Gallery by 10Web: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Photo Gallery by 10Web 1.5.55 closes this, and updating the plugin is the step that ends it.
