CVE-2025-48927

Estado: AnalizadaMedia (5.3)⚠ Explotación activa

The TeleMessage service through 2025-05-05 configures Spring Boot Actuator with an exposed heap dump endpoint at a /heapdump URI, as exploited in the wild in May 2025.

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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

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

Endpoint expuesto sin autenticación (AV:N/PR:N) en servicio web permite descarga de heap dump con datos sensibles en memoria (CWE-1188, confirmado en wild).

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.
