CVE-2012-4578

Status: ModifiedLow (2.1)—

The geli encryption provider 7 before r239184 on FreeBSD 10 uses a weak Master Key, which makes it easier for local users to defeat a cryptographic protection mechanism via a brute-force attack.

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).
