CVE-2026-85441

Estado: Pendiente de análisisAlta (8.7)—

MOOS core-moos through 10.4.0 fails to validate that serialized string lengths are non-negative in CMOOSMsg::operator>>. Unauthenticated attackers can send a crafted message with a negative length value to the MOOSDB port, causing an unhandled exception that terminates the database process.

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.

Vector AV:N/PR:N/UI:N indica exposición remota sin autenticación; mensaje artesanal en puerto MOOSDB causa excepción no manejada → negación de servicio de aplicación (crash del proceso MOOSDB).

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.
