How to Fix CVE-2021-42010

To remediate this vulnerability, upgrade all affected Heron api 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.heron:heron-api fixed: 0.20.5-incubating 
<dependency>
    <groupId>org.apache.heron</groupId>
    <artifactId>heron-api</artifactId>
    <version>0.20.5-incubating</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.heron

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2021-42010, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Heron api in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.20.5-incubating), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.heron 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-116: Improper Encoding or Escaping of Output, where the product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. as a result, the intended structure of the message is not preserved. In Heron api, 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

Heron versions <= 0.20.4-incubating allows CRLF log injection because of the lack of escaping in the log statements. Please update to version 0.20.5-incubating which addresses this issue.
