CVE-2023-2493
At a glance
CVE-2023-2493 is a medium-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the All In One Redirection WordPress plugin, affecting versions <= 2.1.0. It carries a CVSS score of 6.6 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 2.2.0; sites on affected versions should update now. Disclosed June 2023, reported by Chien Vuong.
Vulnerability Overview
The All In One Redirection plugin for WordPress is vulnerable to SQL Injection via the request URI in versions up to, and including, 2.1.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers with administrator capabilities 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, 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 All In One Redirection <= 2.1.0 takes an account at Administrator level or above. 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 All In One Redirection the fix is 2.2.0: builds <= 2.1.0 are affected, anything from 2.2.0 onward is not.
Remediation
Update to version 2.2.0, or a newer patched version
How does WordSec protect against this?
An attacker needs Administrator access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: All In One Redirection 2.2.0 closes this, and updating the plugin is the step that ends it.
