CVE-2021-21380Network attack vector

Database modification via unescaped rating query arguments

Published Mar 23, 2021 · Updated Aug 3, 2024

SQL injection in XWiki Platform 6.4-milestone-3 through 12.8 allows remote authenticated users to alter database data. The Rating Script Service's getAverageRating method passes its fromsql and wheresql arguments directly to AbstractRatingManager, which builds an SQL request without escaping them. Reachability requires the Ratings API to be installed and an account with Script rights; injected SQL can modify database contents, while the CNA reports no direct confidentiality or availability impact.
