Learn about the impact of CVE-2020-0601, a spoofing vulnerability in Windows CryptoAPI, allowing attackers to exploit trust by signing malicious executables with fake certificates. Find mitigation steps here.
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'.
