What CVE is EternalBlue?
Details. EternalBlue exploits a vulnerability in Microsoft’s implementation of the Server Message Block (SMB) protocol. This vulnerability is denoted by entry CVE-2017-0144 in the Common Vulnerabilities and Exposures (CVE) catalog.
Is EternalBlue a buffer overflow?
EternalBlue (patched by Microsoft via MS17-010) is a security flaw related to how a Windows SMB 1.0 (SMBv1) server handles certain requests. If successfully exploited, it can allow attackers to execute arbitrary code in the target system.
How does EternalBlue SMB exploit work?
The EternalBlue exploit works by taking advantage of SMBv1 vulnerabilities present in older versions of Microsoft operating systems. EternalBlue exploits SMBv1 vulnerabilities to insert malicious data packets and spread malware over the network.

How long has Eternal Blue been in circulation?
Two years is a long-time in cybersecurity, but Eternalblue (aka “EternalBlue”, “Eternal Blue”), the critical exploit leaked by the Shadow Brokers and deployed in the WannaCry and NotPetya attacks, is still making the headlines.
What kind of function does EternalBlue rely on?
Eternalblue relies on a Windows function named srv!SrvOS2FeaListSizeToNt. To see how this leads to remote code execution, let’s take a quick look at how SMB works. Primarily, SMB (Server Message Block) is a protocol used to request file and print services from server systems over a network.
How does the EternalBlue exploit work for WannaCry?
EternalBlue is one of the handful of “exploitation tools” leaked by a group called The Shadow Brokers (TSB) that take advantage of weaknesses in how Windows implemented the Server Message Block (SMB) protocol. The WannaCry and NotPetya ransomware strains used this exploit to target unpatched systems.
Who is the creator of the EternalBlue exploit?
EternalBlue is both the given name to a series of Microsoft software vulnerabilities and the exploit created by the NSA as a cyberattack tool.
