Nintendo Wii U OS 5.5.5 - SSL Forgery

Title source: llm
STIX 2.1

Description

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).
