CVE-2026-101292

Estado: Pendiente de análisisAlta (8.2)—

Apache ActiveMQ Artemis before 2.34.0 contains an unsafe reflection vulnerability in FederationStreamConnectMessage.getFederationPolicy(). The method calls Class.forName(clazz).getConstructor().newInstance() where clazz is read directly from the CORE protocol wire buffer without type validation. An authenticated federation peer can send a FEDERATION_DOWNSTREAM_CONNECT packet with a crafted class name, causing the broker to load and instantiate arbitrary classes visible to the Artemis module classloader. Static initializers (<clinit>) and no-argument constructors (<init>()) execute as side effects before the type cast, enabling denial of service via system-property poisoning, out-of-memory conditions via classloading, or broker state manipulation.

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 de reflexión insegura en protocolo CORE de ActiveMQ sin autenticación requerida (AV:N/PR:N). Carga arbitraria de clases ejecuta inicializadores estáticos causando DoS, manipulación de estado del broker e impacto en confidencialidad (CWE-470).

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.
