CVE-2024-21066

Complete database data disclosure to local privileged users

Published Apr 16, 2024 · Updated Nov 1, 2024

Information disclosure in the RDBMS component of Oracle Database 19.3 through 19.22 and 21.3 through 21.13 allows local users to read database data. Oracle has not published the flawed operation or RDBMS code path that mishandles attacker-controlled input. Exploitation requires a high-privileged authenticated account, local infrastructure logon, and another person's interaction; successful attacks expose critical data or all data accessible to the RDBMS.
