CVE-2023-27868Network attack vector

Authenticated code execution via unchecked plugin instantiation

Published Jul 8, 2023 · Updated Feb 13, 2025

Code injection in the IBM Db2 JDBC Driver 10.5, 11.1, and 11.5 allows remote authenticated users to execute arbitrary code. The driver accepts a named pluginClassName value and instantiates the supplied plugin class without validating that the class is safe or permitted. Exploitation requires authenticated network access to an application using the driver and grants code execution with that application's privileges.
