CVE-2020-0601
CVE-2020-0601
En resumen
Windows CryptoAPI no valida correctamente certificados ECC, permitiendo que atacantes creen certificados falsos que parecen legítimos. Esto permite que código malicioso aparezca como proveniente de fuentes confiables, engañando a usuarios y sistemas.
Detalle técnico
CryptoAPI (Crypt32.dll) valida inadecuadamente certificados de Criptografía de Curva Elíptica, habilitando ataques de falsificación de certificados. Un atacante puede crear un certificado de firma de código malicioso que elude las verificaciones de validación, permitiendo que ejecutables sin firmar o maliciosamente firmados parezcan legitimamente firmados por editores de confianza.
Resumen generado y traducido por IA a partir de la descripción 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'.
