You can find this query in the IT Hygiene portion of the catalog named Rogue Share Detection. [5][7][8][9][10][11]:1 On June 27, 2017, the exploit was again used to help carry out the 2017 NotPetya cyberattack on more unpatched computers. inferences should be drawn on account of other sites being The CVE Program has begun transitioning to the all-new CVE website at its new CVE.ORG web address. The agency then warned Microsoft after learning about EternalBlue's possible theft, allowing the company to prepare a software patch issued in March 2017,[18] after delaying its regular release of security patches in February 2017. A race condition was found in the way the Linux kernel's memory subsystem handles the . Oftentimes these trust boundaries affect the building blocks of the operating system security model. Worldwide, the Windows versions most in need of patching are Windows Server 2008 and 2012 R2 editions. We urge everyone to patch their Windows 10 computers as soon as possible. Customers are urged to apply the latest patch from Microsoft for CVE-2020-0796 for Windows 10. The Equation Groups choice of prefixing their collection of SMBv1 exploits with the name Eternal turned out to be more than apt since the vulnerabilities they take advantage of are so widespread they will be with us for a long time to come. [4], The BlueKeep security vulnerability was first noted by the UK National Cyber Security Centre[2] and, on 14 May 2019, reported by Microsoft. One of the biggest risks involving Shellshock is how easy it is for hackers to exploit. CVE-2020-0796. The exploit is novel in its use of a new win32k arbitrary kernel memory read primitive using the GetMenuBarInfo API, which to the best of our knowledge had not been previously known publicly. On 13 August 2019, related BlueKeep security vulnerabilities, collectively named DejaBlue, were reported to affect newer Windows versions, including Windows 7 and all recent versions up to Windows 10 of the operating system, as well as the older Windows versions. If successfully exploited, this vulnerability could execute arbitrary code with "system" privileges. As of March 12, Microsoft has since released a. for CVE-2020-0796, which is a vulnerability specifically affecting SMB3. Once the attackers achieve this initial overflow, they can take advantage of a third bug in SMBv1 which allows heap spraying, a technique which results in allocating a chunk of memory at a given address. While the protocol recognizes that two separate sub-commands have been received, it assigns the type and size of both packets (and allocates memory accordingly) based only on the type of the last one received. Use of the CVE List and the associated references from this website are subject to the terms of use. Both have a _SECONDARY command that is used when there is too much data to include in a single packet.

Science.gov It didnt take long for penetration testers and red teams to see the value in using these related exploits, and they were soon improved upon and incorporated into the Metasploit framework. [14], EternalBlue exploits a vulnerability in Microsoft's implementation of the Server Message Block (SMB) protocol. [37] Comparatively, the WannaCry ransomware program that infected 230,000 computers in May 2017 only uses two NSA exploits, making researchers believe EternalRocks to be significantly more dangerous. Microsoft recently released a patch for CVE-2020-0796, a critical SMB server vulnerability that affects Windows 10. Whether government agencies will learn their lesson is one thing, but it is certainly within the power of every organization to take the Eternalblue threat seriously in 2019 and beyond. [24], The NSA recommended additional measures, such as disabling Remote Desktop Services and its associated port (TCP 3389) if it is not being used, and requiring Network Level Authentication (NLA) for RDP. Over the last year, researchers had proved the exploitability of BlueKeep and proposed countermeasures to detect and prevent it. In this blog post, we attempted to explain the root cause of the CVE-2020-0796 vulnerability. Using only a few lines of code, hackers can potentially give commands to the hardware theyve targeted without having any authorization or administrative access. In addition to disabling SMB compression on an impacted server, Microsoft advised blocking any inbound or outbound traffic on TCP port 445 at the perimeter firewall. An unauthenticated attacker connects to the target system using RDP and sends specially crafted requests to exploit the vulnerability. There is also an existing query in the CBC Audit and Remediation query catalog that can be used to detect rogue SMB shares within your network. [5][6], Both the U.S. National Security Agency (which issued its own advisory on the vulnerability on 4 June 2019)[7] and Microsoft stated that this vulnerability could potentially be used by self-propagating worms, with Microsoft (based on a security researcher's estimation that nearly 1 million devices were vulnerable) saying that such a theoretical attack could be of a similar scale to EternalBlue-based attacks such as NotPetya and WannaCry. Please let us know, GNU Bourne-Again Shell (Bash) Arbitrary Code Execution Vulnerability, Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection').
