At a glance
CVE-2023-0261 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WP TripAdvisor Review Slider WordPress plugin, affecting versions <= 10.7. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 10.8; sites on affected versions should update now. Disclosed January 2023, reported by István Márton.
Vulnerability Overview
The WP TripAdvisor Review Slider plugin for WordPress is vulnerable to SQL Injection via the $tid value in versions up to, and including, 10.7 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 subscriber-level permissions and above 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 WP TripAdvisor Review Slider <= 10.7 takes an account at Subscriber 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 WP TripAdvisor Review Slider the fix is 10.8: builds <= 10.7 are affected, anything from 10.8 onward is not.
Remediation
Update to version 10.8, or a newer patched version
How does WordSec protect against this?
An attacker needs Subscriber 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: WP TripAdvisor Review Slider 10.8 closes this, and updating the plugin is the step that ends it.
