CVE-2012-1809

Status: ModifiedMedium (5)—

The web server in the ECOM Ethernet module in Koyo H0-ECOM, H0-ECOM100, H2-ECOM, H2-ECOM-F, H2-ECOM100, H4-ECOM, H4-ECOM-F, and H4-ECOM100 allows remote attackers to cause a denial of service (resource consumption) 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).
