CVE-2026-66713

Estado: AnalizadaCrítica (9.8)—

Deserialization of Untrusted Data (CWE-502) in the Tribes-based clustering component

in Apache Software Foundation Apache Axis2/Java through 2.0.0 on Apache Tomcat

(only when Tribes clustering is enabled, which is off by default) allows an

unauthenticated remote attacker with network access to the clustering port to

execute arbitrary code via a crafted serialized Java object delivered to the cluster

channel and deserialized in

org.apache.axis2.clustering.tribes.Axis2ChannelListener#messageReceived. Users are

recommended to upgrade to version 2.0.1, which fixes this issue by removing the

clustering feature entirely.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad remota CWE-502 (deserialización de datos no confiables) en puerto de clustering de Axis2, accesible sin autenticación (AV:N/PR:N/UI:N), permitiendo ejecución arbitraria de código Java.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
