CVE-2021-24753Public exploitNetwork attack vector

Authenticated database access via unvalidated orderby parameter

Published Dec 27, 2021 · Updated Aug 3, 2024

SQL injection in Starfish Reviews Rich Reviews before 1.9.6 allows remote authenticated users to access WordPress database data. The pending-reviews page inserts the orderby GET parameter into a SQL statement without proper validation, enabling crafted database expressions. WordPress administrator access to that page is required, and the published proof of concept demonstrates error-based extraction and time-based query execution.
