CVE-2026-33728

Status: AnalyzedCritical (9.3)—

dd-trace-java is a Datadog APM client for Java. In versions of dd-trace-java 0.40.0 through prior to 1.60.2, the RMI instrumentation registered a custom endpoint that deserialized incoming data without applying serialization filters. On JDK version 16 and earlier, an attacker with network access to a JMX or RMI port on an instrumented JVM could exploit this to potentially achieve remote code execution. All three of the following conditions must be true to exploit this vulnerability: First, dd-trace-java is attached as a Java agent (`-javaagent`) on Java 16 or earlier.

Second, a JMX/RMI port has been explicitly configured via `-Dcom.sun.management.jmxremote.port` and is network-reachable, Third, a gadget-chain-compatible library is present on the classpath. For JDK >= 17, no action is required, but upgrading is strongly encouraged. For JDK >= 8u121 < JDK 17, upgrade to dd-trace-java version 1.60.3 or later. For JDK < 8u121 and earlier where serialization filters are not available, apply the workaround. The workaround is to set the following environment variable to disable the RMI integration: `DD_INTEGRATION_RMI_ENABLED=false`.

      "value": "dd-trace-java es un cliente APM de Datadog para Java. En las versiones de dd-trace-java 0.40.0 hasta la anterior a 1.60.2, la instrumentación RMI registró un punto final personalizado que deserializaba los datos entrantes sin aplicar filtros de serialización. En la versión 16 de JDK y anteriores, un atacante con acceso de red a un puerto JMX o RMI en una JVM instrumentada podría explotar esto para lograr potencialmente la ejecución remota de código. Las tres condiciones siguientes deben ser verdaderas para explotar esta vulnerabilidad: Primero, dd-trace-java está adjunto como un agente Java ('-javaagent') en Java 16 o anterior. Segundo, un puerto JMX/RMI ha sido configurado explícitamente a través de '-Dcom.sun.management.jmxremote.port' y es accesible por red. Tercero, una biblioteca compatible con cadenas de gadgets está presente en el classpath. Para JDK &gt;= 17, no se requiere ninguna acción, pero se recomienda encarecidamente la actualización. Para JDK &gt;= 8u121 &lt; JDK 17, actualice a la versión 1.60.3 o posterior de dd-trace-java. Para JDK &lt; 8u121 y anteriores donde los filtros de serialización no están disponibles, aplique la solución alternativa. La solución alternativa es establecer la siguiente variable de entorno para deshabilitar la integración RMI: 'DD_INTEGRATION_RMI_ENABLED=false'."
