How to Fix CVE-2022-43766

To remediate this vulnerability, upgrade all affected Flink tsfile connector 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.iotdb:flink-tsfile-connector fixed: 0.13.3 
<dependency>
    <groupId>org.apache.iotdb</groupId>
    <artifactId>flink-tsfile-connector</artifactId>
    <version>0.13.3</version>
</dependency>
apache-iotdb fixed: 0.13.3 
pip install apache-iotdb>=0.13.3
org.apache.iotdb:iotdb-server fixed: 0.13.3 
<dependency>
    <groupId>org.apache.iotdb</groupId>
    <artifactId>iotdb-server</artifactId>
    <version>0.13.3</version>
</dependency>
org.apache.iotdb:tsfile fixed: 0.13.3 
<dependency>
    <groupId>org.apache.iotdb</groupId>
    <artifactId>tsfile</artifactId>
    <version>0.13.3</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.iotdb

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-43766, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Flink tsfile connector in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.13.3), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.iotdb 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Flink tsfile connector, 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

Apache IoTDB versions 0.12.2 through 0.12.6, and 0.13.0 through 0.13.2 are vulnerable to a Denial of Service attack when accepting untrusted patterns for REGEXP queries with Java 8. This issue is patched in 0.13.3. Users should upgrade or use a later version of Java to avoid it.
