CVE-2026-49434

Estado: AnalizadaAlta (7.5)—

Improper Input Validation vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ, Apache ActiveMQ All.

An attacker that has access to publish or modify entries in LDAP that match the configured searchBase and searchFilter can instantiate denied transports inside the broker JVM. This can be used to fetch an attacker URL and spawn a second BrokerService inside the same JVM. This issue affects Apache ActiveMQ Broker: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ All: before 5.19.8, from 6.0.0 before 6.2.7.

Users are recommended to upgrade to version 6.2.7 or 5.19.8, which fixes the issue.

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.

AV:N/PR:N permite T1190 (aplicación expuesta). El acceso a LDAP y creación de BrokerService sugiere ejecución de código arbitrario (T1059) e instanciación de servicios adicionales (T1578.003 para recursos bajo control adversario).

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.
