17-Year-Old Critical 'Wormable' RCE Vulnerability Impacts Windows DNS Servers

17-Year-Old Critical 'Wormable' RCE Vulnerability Impacts Windows DNS Servers

Jul 14, 2020
Cybersecurity researchers today disclosed a new highly critical "wormable" vulnerability—carrying a severity score of 10 out of 10 on the CVSS scale—affecting Windows Server versions 2003 to 2019. The 17-year-old remote code execution flaw ( CVE-2020-1350 ), dubbed ' SigRed ' by Check Point, could allow an unauthenticated, remote attacker to gain domain administrator privileges over targeted servers and seize complete control of an organization's IT infrastructure. A threat actor can exploit SigRed vulnerability by sending crafted malicious DNS queries to a Windows DNS server and achieve arbitrary code execution, enabling the hacker to intercept and manipulate users' emails and network traffic, make services unavailable, harvest users' credentials and much more. In a detailed report shared with The Hacker News, Check Point researcher Sagi Tzadik confirmed that the flaw is wormable in nature, allowing attackers to launch an attack that can spread ...
Critical Patch Released for 'Wormable' SMBv3 Vulnerability — Install It ASAP!

Critical Patch Released for 'Wormable' SMBv3 Vulnerability — Install It ASAP!

Mar 12, 2020
Microsoft today finally released an emergency software update to patch the recently disclosed very dangerous vulnerability in SMBv3 protocol that could let attackers launch wormable malware , which can propagate itself from one vulnerable computer to another automatically. The vulnerability, tracked as CVE-2020-0796 , in question is a remote code execution flaw that impacts Windows 10 version 1903 and 1909, and Windows Server version 1903 and 1909. Server Message Block (SMB), which runs over TCP port 445, is a network protocol that has been designed to enable file sharing, network browsing, printing services, and interprocess communication over a network. The latest vulnerability, for which a patch update ( KB4551762 ) is now available on the Microsoft website, exists in the way SMBv3 protocol handles requests with compression headers, making it possible for unauthenticated remote attackers to execute malicious code on target servers or clients with SYSTEM privileges. Compre...
5 Reasons Device Management Isn't Device Trust​

5 Reasons Device Management Isn't Device Trust​

Apr 21, 2025Endpoint Security / Zero Trust
The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...
Warning — Unpatched Critical 'Wormable' Windows SMBv3 Flaw Disclosed

Warning — Unpatched Critical 'Wormable' Windows SMBv3 Flaw Disclosed

Mar 11, 2020
Shortly after releasing its monthly batch of security updates , Microsoft late yesterday separately issued an advisory warning billions of its Windows users of a new critical, unpatched, and wormable vulnerability affecting Server Message Block 3.0 ( SMBv3 ) network communication protocol. It appears Microsoft originally planned to fix the flaw as part of its March 2020 Patch Tuesday update only, but, for some reason, it pulled the plug at the last minute, which apparently did not stop a tech company from accidentally leaking the existence of the unpatched flaw. The yet-to-be patched flaw (tracked as CVE-2020-0796 ), if exploited successfully, could allow an attacker to execute arbitrary code on the target SMB Server or SMB Client. The belated acknowledgment from Microsoft led some researchers to call the bug " SMBGhost ." "To exploit the vulnerability against an SMB Server, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv3...
