| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2012-1809 | 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. | [email protected] | 5.0 | 1.36% | 2012-04-13 | 2026-06-16 |
| CVE-2012-1808 | 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 does not require authentication, which allows remote attackers to perform unspecified functions via unknown vectors. | [email protected] | 10.0 | 3.58% | 2012-04-13 | 2026-06-16 |
| CVE-2012-1807 | Cross-site scripting (XSS) vulnerability in 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 inject arbitrary web script or HTML via unspecified vectors. | [email protected] | 4.3 | 1.01% | 2012-04-13 | 2026-06-16 |
| CVE-2012-1806 | 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 supports a maximum password length of 8 bytes, which makes it easier for remote attackers to obtain access via a brute-force attack. | [email protected] | 7.5 | 2.07% | 2012-04-13 | 2026-06-16 |
