CVE-2015-2906

Status: ModifiedHigh (9)—

Mobile Devices (aka MDI) C4 OBD-II dongles with firmware 2.x and 3.4.x, as used in Metromile Pulse and other products, store SSH private keys that are the same across different customers' installations, which makes it easier for remote attackers to obtain access by leveraging knowledge of a private key from another installation.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
