Similarly if an attacker could convince or trick a user into connecting to a malicious SMBv3 Server, then the users SMB3 client could also be exploited. To see how this leads to remote code execution, lets take a quick look at how SMB works. They were made available as open sourced Metasploit modules. This has led to millions of dollars in damages due primarily to ransomware worms. RDP 5.1 defines 32 "static" virtual channels, and "dynamic" virtual channels are contained within one of these static channels. Among the protocols specifications are structures that allow the protocol to communicate information about a files extended attributes, essentially metadata about the files properties on the file system. Site Privacy While the author of that malware shut down his operation after intense media scrutiny, other bad actors may have continued similar work as all the tools required were present in the original leak of Equation Groups tool kit. Specifically this vulnerability would allow an unauthenticated attacker to exploit this vulnerability by sending a specially crafted packet to a vulnerable SMBv3 Server. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. Using only a few lines of code, hackers can potentially give commands to the hardware theyve targeted without having any authorization or administrative access.
