CVE-2020-0601
CVE-2020-0601
Em resumo
O Windows CryptoAPI não valida corretamente certificados ECC, permitindo que atacantes criem certificados falsos que parecem legítimos. Isso permite que código malicioso apareça como originário de fontes confiáveis, enganando usuários e sistemas.
Detalhe técnico
CryptoAPI (Crypt32.dll) valida inadequadamente certificados de Criptografia de Curva Elíptica, viabilizando ataques de falsificação de certificados. Um atacante pode criar um certificado de assinatura de código malicioso que ultrapassa as verificações de validação, permitindo que executáveis não assinados ou maliciosamente assinados pareçam legitimamente assinados.
Resumo gerado e traduzido por IA a partir da descrição oficial.
A spoofing vulnerability exists in the way Windows CryptoAPI (Crypt32.dll) validates Elliptic Curve Cryptography (ECC) certificates.An attacker could exploit the vulnerability by using a spoofed code-signing certificate to sign a malicious executable, making it appear the file was from a trusted, legitimate source, aka 'Windows CryptoAPI Spoofing Vulnerability'.
