CVE-2020-5633

Status: ModifiedCritical (9.8)—

Multiple NEC products (Express5800/T110j, Express5800/T110j-S, Express5800/T110j (2nd-Gen), Express5800/T110j-S (2nd-Gen), iStorage NS100Ti, and Express5800/GT110j) where Baseboard Management Controller (BMC) firmware Rev1.09 and earlier is applied allows remote attackers to bypass authentication and then obtain/modify BMC setting information, obtain monitoring information, or reboot/shut down the vulnerable product via unspecified vectors.

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).
