CVE-1999-1420

Status: ModifiedHigh (10)—

NBase switches NH2012, NH2012R, NH2015, and NH2048 have a back door password that cannot be disabled, which allows remote attackers to modify the switch's configuration.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
Base score: 10

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 2.90%
Percentile among all scored CVEs: 87
Score date: 10/12/2026

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).
