CVE-2020-37159

Estado: AplazadaAlta (8.4)—

Parallaxis Cuckoo Clock 5.0 contains a buffer overflow vulnerability that allows attackers to execute arbitrary code by overwriting memory registers in the alarm scheduling feature. Attackers can craft a malicious payload exceeding 260 bytes to overwrite EIP and EBP, enabling shellcode execution with potential remote code execution.

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.

Buffer overflow local con interacción del usuario (UI:A) en característica de alarma. Requiere abrir archivo malicioso (260+ bytes) → T1203. Ejecución arbitraria de código mediante sobrescritura de registros (EIP/EBP) y shellcode.

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.
