CVE-2023-29257Network attack vector

Cross-database code execution via undisclosed isolation failure

Published Apr 26, 2023 · Updated Feb 13, 2025

Remote code execution in IBM Db2 10.5, 11.1, and 11.5 allows remote authenticated users to cross database boundaries. IBM has not disclosed the affected Db2 functionality or the operation that fails to enforce database-level isolation. Database-administrator privileges on one database are required; exploitation executes code or reads and writes files from another database in the same instance.
