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.

Jan 16, 2020 · A flaw (CVE-2020-0601) has recently been found in the way the Microsoft Windows CryptoAPI performs certificate validation, allowing attackers to spoof X.509 vulnerabilities. This is core cryptographic functionality used by a number of different software components, with far-reaching impact ranging from programming languages to web browsers. An update is available for Windows Embedded CE 6.0 R3. This update enables CryptoAPI 2.0 APIs to support the Secure Hash Algorithm 2 (SHA2) signature algorithm. After you apply this update, the trust level of a server certificate that uses the SHA2 signature algorithm can be verified in a Secure Socket Layer (SSL) connection when the certificate is in the root store. The read-only Window.crypto property returns the Crypto object associated to the global object. This object allows web pages access to certain cryptographic related services. Jan 16, 2020 · Yes, there was a big bad bug, and it was in the Windows CryptoAPI. It wasn’t a wormable remote code execution hole , so it wasn’t quite a WannaCry virus waiting to break out… Jun 05, 2019 · On Windows 2003, Crypto API does not check static proxy settings. 2.) 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. The Microsoft CryptoAPI provides services that enable developers to secure Windows-based applications using cryptography, and includes functionality for encrypting and decrypting data using

Jan 14, 2020 · The CryptoAPI is what enables developers to secure Windows-based applications and any critical vulnerability here could impact encryption and decryption using digital certificates.

The Microsoft Windows platform specific Cryptographic Application Programming Interface (also known variously as CryptoAPI, Microsoft Cryptography API, MS-CAPI or simply CAPI) is an application programming interface included with Microsoft Windows operating systems that provides services to enable developers to secure Windows-based applications using cryptography. CryptoAPI System Architecture. 05/31/2018; 2 minutes to read; In this article. The CryptoAPI system architecture is composed of five major functional areas: Base Cryptographic Functions; Certificate Encode/Decode Functions; Certificate Store Functions; Simplified Message Functions; Low-level Message Functions; Base Cryptographic Functions CryptoAPI is intended for use by developers of Windows-based applications that will enable users to create and exchange documents and other data in a secure environment, especially over nonsecure media such as the Internet. Developers should be familiar with the C and C++ programming languages and the Windows programming environment. Jan 14, 2020 · "A spoofing vulnerability exists in the way Windows CryptoAPI (Crypt32.dll) validates Elliptic Curve Cryptography (ECC) certificates," says Microsoft's security advisory.
