CVE-2018-13435

Estado: ModificadaAlta (7)—

** EN DISPUTA ** Se ha descubierto un problema en la aplicación LINE jp.naver.line 8.8.0 para iOS. La característica Passcode permite la omisión de autenticación mediante la manipulación del tiempo de ejecución que fuerza a un determinado método a deshabilitar la autenticación de código de acceso. NOTA: el fabricante indica que esto no es un ataque de interés en el contexto del modelo de amenazas, lo que excluye a los dispositivos iOS que tienen jailbreak.

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).
