CVE-2020-36986

Estado: AplazadaAlta (8.5)—

Prey 1.9.6 contains an unquoted service path vulnerability that allows local users to potentially execute code with elevated privileges. Attackers can exploit the unquoted path in the CronService to insert malicious code that would execute during application startup or system reboot.

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.

Acceso local con privilegios (PR:L) sin interacción del usuario (UI:N) en servicio vulnerable con path sin entrecomillar permite escalada a código ejecutado con privilegios elevados (VC:H, VI:H, VA:H).

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.
