CVE-2024-1300 at a Glance
Security Impact
CVSS: 5.4
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L).
How to Fix CVE-2024-1300
To remediate this vulnerability, upgrade all affected Vertx core 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.vertx</groupId>
<artifactId>vertx-core</artifactId>
<version>4.4.8</version>
</dependency><dependency>
<groupId>io.vertx</groupId>
<artifactId>vertx-core</artifactId>
<version>4.5.3</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.vertxHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2024-1300, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=io.vertxAnalyze the terminal output to locate any version of Vertx core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.4.8), your application is affected.
Note: The mvn dependency:tree -Dincludes=io.vertx 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.

When processing an unknown SNI server name assigned the default certificate instead of a mapped certificate, the SSL context is erroneously cached in the server name map, leading to memory exhaustion. This flaw allows attackers to send TLS client hello messages with fake server names, triggering a JVM out-of-memory error.",
