CVE-2018-3832

Estado: ModificadaCrítica (9)—

An exploitable firmware update vulnerability exists in Insteon Hub running firmware version 1013. The HTTP server allows for uploading arbitrary MPFS binaries that could be modified to enable access to hidden resources which allow for uploading unsigned firmware images to the device. To trigger this vulnerability, an attacker can upload an MPFS binary via the '/mpfsupload' HTTP form and later on upload the firmware via a POST request to 'firmware.htm'.

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).
