One of the most notable vulnerabilities patched during Microsoft's first Patch Tuesday of 2020 was a spoofing vulnerability in the Windows CryptoAPI. This has been issued CVE-2020-0601 and has also been referred to as the "Curveball" or "Chain of Fools" vulnerability.

The Microsoft CryptoAPI provides services that enable developers to secure Windows-based applications using cryptography, and includes functionality for encrypting and decrypting data using Feb 28, 2020 · McAfee is aware of the recent Windows CryptoAPI Spoofing vulnerability (CVE-2020-0601). We have technology in development to detect the vulnerability and are currently conducting rigorous quality assurance and efficacy testing. We strongly advise rapid deployment of the Microsoft patches released on January 14. Daisy has received a notification of a vulnerability (CVE-2020-0601) that affects a number of Windows versions . The flaw exists in Microsoft’s Crypto API (crypt32.dll) which handles encryption and digital signatures. The vulnerability enables an attacker to perform a number of malicious actions against affected systems such as spoofing signed files and email. Spoofing signed Jan 16, 2020 · Current Description . 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'.

If a statically configured proxy is not found, the Crypto API tries to retrieve the Internet Explorer proxy settings for the user context under which the Crypto API is executing.

Jan 14, 2020 · Description. The Microsoft Windows CryptoAPI, which is provided by Crypt32.dll, fails to validate ECC certificates in a way that properly leverages the protections that ECC cryptography should provide. As a result, an attacker may be able to craft a certificate that appears to have the ability to be traced to a trusted root certificate authority. Any software, including third-party non-Microsoft software, that relies on the Windows CertGetCertificateChain () function to determine if an X.509

Jun 03, 2003 · This is a technical article for Windows Cryptography programmers. Introduction This article shows how to set the RC4 key used by the Microsoft Windows CryptoAPI Win32 routines to do encryption or decryption. Surprisingly there is no explicit way to set a known key. Instead, a key must be encrypted by a second key before it can be used. Jan 17, 2020 · What is CVE-2020-0601 . As a reminder, there is a spoofing vulnerability CVE-2020-0601 in the Crypt32.dll library (CryptoAPI) that could be exploited by an attacker. An attacker could use a spoofed code-signing certificate to sign a malicious executable file without Windows knowing about it. Jan 14, 2020 · The Microsoft CryptoAPI enables developers to cryptographically secure Windows applications. For this purpose there are functions for encrypting and decrypting data with the help of digital certificates. A critical vulnerability in this Windows component could have far-reaching effects on the security of a number of important Windows functions.
