CVE-2018-7933

Estado: ModificadaAlta (7.8)—

Huawei home gateway products HiRouter-CD20 and WS5200 with the versions before HiRouter-CD20-10 1.9.6 and the versions before WS5200-10 1.9.6 have a path traversal vulnerability. Due to the lack of validation while these home gateway products install APK plugins, an attacker tricks a user into installing a malicious APK plugin, and plugin can overwrite arbitrary file of devices. Successful exploit may result in arbitrary code execution or privilege escalation.

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).
