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'.
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'.
A Windows vulnerability allows attackers to spoof valid certificate chains when the system root store is in use. A workaround is present in Go 1.12.6+ and Go 1.13.7+, but affected users should additionally install the Windows security update to protect their system. See https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2020-0601 for details on the Windows vulnerability.
Se presenta una vulnerabilidad de suplantación de identidad en la manera en que Windows CryptoAPI (Crypt32.dll) comprueba los certificados Elliptic Curve Cryptography (ECC). Un atacante podría explotar la vulnerabilidad mediante el uso de un certificado de firma de código falsificado para firmar un ejecutable malicioso, haciendo que parezca que el archivo era de una fuente confiable y legítima, también se conoce como "Windows CryptoAPI Spoofing Vulnerability".
