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.
The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete.
The product compares two entities in a security-relevant context, but the comparison is incorrect, which may lead to resultant weaknesses.
