CVE-2026-6351

Estado: AplazadaAlta (8.7)—

MailGates/MailAudit developed by Openfind has a CRLF Injection vulnerability, allowing unauthenticated remote attackers to exploit this vulnerability to read system files.

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 CVSS:4.0/AV:N/AC:L/PR:N/UI:N indica acceso remoto sin autenticación. CRLF injection en MailGates permite leer archivos del sistema (CWE-93, inyección de protocolos).

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.
