FKIE_CVE-2024-34454

Vulnerability from fkie_nvd - Published: 2024-05-26 22:15 - Updated: 2026-06-17 07:33
Severity
7.4 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N
Summary
Nintendo Wii U OS 5.5.5 allows man-in-the-middle attackers to forge SSL certificates as though they came from a Root CA, because there is a secondary verification mechanism that only checks whether a CA is known and ignores the CA details and signature (and because * is accepted as a Common Name).
