How to Fix CVE-2023-34468

To remediate this vulnerability, upgrade all affected Nifi dbcp base dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.apache.nifi:nifi-dbcp-base fixed: 1.22.0 
<dependency>
    <groupId>org.apache.nifi</groupId>
    <artifactId>nifi-dbcp-base</artifactId>
    <version>1.22.0</version>
</dependency>
org.apache.nifi:nifi-hikari-dbcp-service fixed: 1.22.0 
<dependency>
    <groupId>org.apache.nifi</groupId>
    <artifactId>nifi-hikari-dbcp-service</artifactId>
    <version>1.22.0</version>
</dependency>
org.apache.nifi:nifi-dbcp-service-nar fixed: 1.22.0 
<dependency>
    <groupId>org.apache.nifi</groupId>
    <artifactId>nifi-dbcp-service-nar</artifactId>
    <version>1.22.0</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.apache.nifi

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-34468, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.nifi

Analyze the terminal output to locate any version of Nifi dbcp base in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.22.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.nifi command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Nifi dbcp base, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The DBCPConnectionPool and HikariCPConnectionPool Controller Services in Apache NiFi 0.0.2 through 1.21.0 allow an authenticated and authorized user to configure a Database URL with the H2 driver that enables custom code execution. The resolution validates the Database URL and rejects H2 JDBC locations. You are recommended to upgrade to version 1.22.0 or later which fixes this issue.
