A path traversal vulnerability in the iclock API of ZKTeco BioTime v8.5.5 allows unauthenticated attackers to read arbitrary files via supplying a crafted payload. This vulnerability was fixed in version 9.0.120240617.19506 of ZKBioTime.

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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad de traversal de rutas (CWE-22) en API sin autenticación (PR:N, UI:N) permite lectura arbitraria de archivos. Vector AV:N/AC:L confirma explotación remota directa (T1190) con acceso a datos (T1005).

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.
