CVE-2020-2510Public exploitNetwork attack vector

Core RDBMS takeover via gateway version SQL injection

Published Jan 15, 2020 · Updated Sep 30, 2024

SQL injection in Oracle Database Core RDBMS 11.2.0.4, 12.1.0.2, 12.2.0.1, 18c, and 19c allows remote attackers to take over the service via OracleNet. A linked database gateway's untrusted version string is incorporated into SQL and can reference a function that executes as a privileged database user. The database must query a malicious or intercepted gateway, so exploitation requires another person's interaction and can expose or alter database data or interrupt the service.
