How to Fix CVE-2023-3223
To remediate this vulnerability, upgrade all affected Undertow parent 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>io.undertow</groupId>
<artifactId>undertow-parent</artifactId>
<version>2.2.24.Final</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=io.undertowHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2023-3223, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=io.undertowAnalyze the terminal output to locate any version of Undertow parent in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2.24.Final), your application is affected.
Note: The mvn dependency:tree -Dincludes=io.undertow 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-789: Memory Allocation with Excessive Size Value, where the product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated. In Undertow parent, 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.
