The 2017 Pwnie Award For Best Server-Side Bug
CVE-2017-0143, 0144, 0145
These vulnerabilities allow arbitrary remote command execution on Microsoft Operating Systems running the SMB file sharing protocol, which is pretty much all MSFT systems. The vulnerabilities became known as a result of the Shadow Brokers release of (allegedly) the NSA’s ETERNAL* exploits, which include variations for different OS versions and functions. Multiple ransomware platforms have taken advantage of these vulnerabilities, causing Microsoft to release patched for unsupported systems such as Windows XP.
