CVE-2026-59111

Estado: AplazadaCrítica (9.3)—

Improper neutralization of special elements used in an OS command ('OS command injection') vulnerability in Digitální a informační agentura (DIA) eObčanka-Identifikace on MacOS enables an attacker to register a custom URL scheme (czeeopauth://) for parameterized application execution. Prior to version 3.6.0, incoming URL parameters were passed to the compiled AppleScript wrapper using concatenation without sufficient sanitization.

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.

UI:R + interacción del usuario (URL scheme personalizado) → T1203. OS command injection sin sanitización permite ejecución de comandos arbitrarios (T1059) y potencial acceso a credenciales OAuth (T1078) mediante el esquema ezeeopauth.

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.
