CVE-2023-40037: Apache NiFi: Incomplete Validation of JDBC and JNDI Connection URLs

[David Handermann <exceptionfactory () apache org>]

Severity: moderate

Affected versions:

- Apache NiFi 1.21.0 through 1.23.0

Description:

Apache NiFi 1.21.0 through 1.23.0 support JDBC and JNDI JMS access in several Processors and Controller Services with 
connection URL validation that does not provide sufficient protection against crafted inputs. An authenticated and 
authorized user can bypass connection URL validation using custom input formatting. The resolution enhances connection 
URL validation and introduces validation for additional related properties. Upgrading to Apache NiFi 1.23.1 is the 
recommended mitigation.

This issue is being tracked as NIFI-11920
