How to Fix CVE-2022-42920
To remediate this vulnerability, upgrade all affected Bcel dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.apache.bcel</groupId>
<artifactId>bcel</artifactId>
<version>6.6.0</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.apache.bcelHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2022-42920, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.bcelAnalyze the terminal output to locate any version of Bcel in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.6.0), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.apache.bcel 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.

"details" : "Apache Commons BCEL has a number of APIs that would normally only allow changing specific class characteristics. However, due to an out-of-bounds writing issue, these APIs can be used to produce arbitrary bytecode. This could be abused in applications that pass attacker-controllable data to those APIs, giving the attacker more control over the resulting bytecode than otherwise expected.
