Title

Apache Camel: Camel-Hazelcast: Unsafe Java deserialization in default-configured managed Hazelcast instances enables remote code execution

Summary

Deserialization of Untrusted Data vulnerability in Apache Camel Hazelcast component. The camel-hazelcast component creates and manages Hazelcast instances using a default configuration that applies no Java deserialization filter. When Camel builds the Hazelcast Config itself - that is, when no user-supplied HazelcastInstance, hazelcastConfigUri, or referenced Config bean is provided - neither Hazelcast's JavaSerializationFilterConfig nor a Camel-side ObjectInputFilter is configured, so objects received over the Hazelcast cluster protocol are deserialized inside Hazelcast's own serialization layer (ObjectInputStream.readObject) before Camel ever processes them. An attacker who can join or otherwise reach the Hazelcast cluster can publish a crafted serialized Java object that is then deserialized on every Camel node, resulting in remote code execution. The exposure is present by default and requires no opt-in endpoint configuration: any route using a hazelcast consumer (hazelcast-topic, hazelcast-queue, hazelcast-seda, hazelcast-map, hazelcast-multimap, hazelcast-replicatedmap, hazelcast-list, hazelcast-set), as well as the HazelcastAggregationRepository and HazelcastIdempotentRepository, is affected whenever the managed instance is created from Camel's default configuration. This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0. Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. The fix makes Camel apply a default Hazelcast JavaSerializationFilterConfig (whitelisting the java., javax. and org.apache.camel. class-name prefixes and blacklisting java.net.) to instances it creates from its own default configuration, while leaving any user-supplied Config or HazelcastInstance untouched. For deployments that cannot upgrade immediately, configure a deserialization filter on the Hazelcast instance (Hazelcast JavaSerializationFilterConfig, or the JVM-wide system property -Djdk.serialFilter=!java.net.**;java.**;javax.**;org.apache.camel.**;!*) and enable Hazelcast cluster authentication and TLS to restrict who can reach the cluster.

            "value": "Vulnerabilidad de deserializaci\u00f3n de datos no confiables en el componente Apache Camel Hazelcast.\n\nEl componente camel-hazelcast crea y gestiona instancias de Hazelcast utilizando una configuraci\u00f3n predeterminada que no aplica ning\u00fan filtro de deserializaci\u00f3n de Java. Cuando Camel construye la configuraci\u00f3n de Hazelcast por s\u00ed mismo, es decir, cuando no se proporciona ninguna instancia de Hazelcast, hazelcastConfigUri o bean de configuraci\u00f3n referenciado suministrado por el usuario, ni JavaSerializationFilterConfig de Hazelcast ni un ObjectInputFilter del lado de Camel est\u00e1n configurados, por lo que los objetos recibidos a trav\u00e9s del protocolo de cl\u00faster de Hazelcast son deserializados dentro de la propia capa de serializaci\u00f3n de Hazelcast (ObjectInputStream.readObject) antes de que Camel los procese. Un atacante que puede unirse o de otra manera alcanzar el cl\u00faster de Hazelcast puede publicar un objeto Java serializado manipulado que luego es deserializado en cada nodo de Camel, lo que resulta en ejecuci\u00f3n remota de c\u00f3digo. La exposici\u00f3n est\u00e1 presente por defecto y no requiere configuraci\u00f3n de punto final de aceptaci\u00f3n: cualquier ruta que utilice un consumidor de hazelcast (hazelcast-topic, hazelcast-queue, hazelcast-seda, hazelcast-map, hazelcast-multimap, hazelcast-replicatedmap, hazelcast-list, hazelcast-set), as\u00ed como el HazelcastAggregationRepository y el HazelcastIdempotentRepository, se ve afectada siempre que la instancia gestionada se crea a partir de la configuraci\u00f3n predeterminada de Camel.\nEste problema afecta a Apache Camel: desde 4.0.0 antes de 4.14.8, desde 4.15.0 antes de 4.18.3, desde 4.19.0 antes de 4.21.0.\n\nSe recomienda a los usuarios actualizar a la versi\u00f3n 4.21.0, que corrige el problema. Si los usuarios est\u00e1n en la rama de versiones LTS 4.14.x, se les sugiere actualizar a 4.14.8. Si los usuarios est\u00e1n en la rama de versiones 4.18.x, se les sugiere actualizar a 4.18.3. La correcci\u00f3n hace que Camel aplique un JavaSerializationFilterConfig de Hazelcast predeterminado (incluyendo en la lista blanca los prefijos de nombre de clase java., javax. y org.apache.camel. y en la lista negra java.net.) a las instancias que crea a partir de su propia configuraci\u00f3n predeterminada, dejando intacta cualquier configuraci\u00f3n o instancia de Hazelcast suministrada por el usuario. Para implementaciones que no pueden actualizarse inmediatamente, configure un filtro de deserializaci\u00f3n en la instancia de Hazelcast (Hazelcast JavaSerializationFilterConfig, o la propiedad de sistema a nivel de JVM -Djdk.serialFilter=!java.net.;java.;javax.;org.apache.camel.;!*) y habilite la autenticaci\u00f3n de cl\u00faster de Hazelcast y TLS para restringir qui\u00e9n puede acceder al cl\u00faster."

Summary

Apache Camel-Hazelcast: Unsafe Java deserialization in default-configured managed Hazelcast instances enables remote code execution

Details

Deserialization of Untrusted Data vulnerability in Apache Camel Hazelcast component.

The camel-hazelcast component creates and manages Hazelcast instances using a default configuration that applies no Java deserialization filter. When Camel builds the Hazelcast Config itself - that is, when no user-supplied HazelcastInstance, hazelcastConfigUri, or referenced Config bean is provided - neither Hazelcast's JavaSerializationFilterConfig nor a Camel-side ObjectInputFilter is configured, so objects received over the Hazelcast cluster protocol are deserialized inside Hazelcast's own serialization layer (ObjectInputStream.readObject) before Camel ever processes them. An attacker who can join or otherwise reach the Hazelcast cluster can publish a crafted serialized Java object that is then deserialized on every Camel node, resulting in remote code execution. The exposure is present by default and requires no opt-in endpoint configuration: any route using a hazelcast consumer (hazelcast-topic, hazelcast-queue, hazelcast-seda, hazelcast-map, hazelcast-multimap, hazelcast-replicatedmap, hazelcast-list, hazelcast-set), as well as the HazelcastAggregationRepository and HazelcastIdempotentRepository, is affected whenever the managed instance is created from Camel's default configuration. This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.

Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. The fix makes Camel apply a default Hazelcast JavaSerializationFilterConfig (whitelisting the java., javax. and org.apache.camel. class-name prefixes and blacklisting java.net.) to instances it creates from its own default configuration, while leaving any user-supplied Config or HazelcastInstance untouched. For deployments that cannot upgrade immediately, configure a deserialization filter on the Hazelcast instance (Hazelcast JavaSerializationFilterConfig, or the JVM-wide system property -Djdk.serialFilter=!java.net.;java.;javax.;org.apache.camel.;!*) and enable Hazelcast cluster authentication and TLS to restrict who can reach the cluster.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
