Title: Microsoft patches 49 vulnerabilities as part of Patch Tuesday

Description: Microsoft released its monthly security update today, disclosing vulnerabilities across many of its products and releasing corresponding updates. Patch Tuesday covers 49 vulnerabilities, eight of which are considered critical. This month's security update is particularly important for its disclosure of two vulnerabilities related to a core cryptographic component in all versions of Windows. CVE-2020-0601 could allow an attacker to use cryptography to sign a malicious executable, making the file appear as if it was from a trusted source. The victim would have no way of knowing if the file was malicious. Cyber security reporter Brian Krebs says the vulnerability is so serious, Microsoft secretly deployed a patch to branches of the U.S. military prior to today.

Title: ZeroCleare wiper malware deployed on oil refinery

Description: ZeroCleare, a wiper malware connected to an Iranian hacker group, was recently deployed against a national oil refinery in Bahrain. An upgraded version has been spotted in the wild, according to security researchers, which can delete files off infected machines. The latest attacks match previous attacks using this malware family, which have gone after other targets connected to Saudi Arabia. Concerns over Iranian cyber attacks have spiked since the U.S. killed a high-profile Iranian general in a drone strike.

Vulnerabilities with Exploits


COMPILED BY THE QUALYS VULNERABILITY RESEARCH TEAM


This is a list of recent vulnerabilities for which exploits are

available. System administrators can use this list to help in

prioritization of their remediation activities. The Qualys Vulnerability

Research Team compiles this information based on various exploit

frameworks, exploit databases, exploit kits and monitoring of internet

activity.


ID: CVE-2020-0601

Title: Microsoft Windows CryptoAPI Spoofing Vulnerability

Vendor: Microsoft

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. The user would have no way of knowing the file was malicious, because the digital signature would appear to be from a trusted provider.

A successful exploit could also allow the attacker to conduct man-in-the-middle attacks and decrypt confidential information on user connections to the affected software.
