impacket.dcerpc.v5.rpcrt.DCERPCException: DCERPC Runtime Error: code: 0x5 - rpc_s_access_denied about cve-2021-1675

[hemazoher]

trust me this rpc_s_access_denied = Operation did not complete successfully because the file contains a virus or potentially unwanted software
turn off the real-time protection and windows firewall

Can you confirm that the serv can reach your share without any cred ?

Due to Microsoft's security regulations, domain member cannot access smb outside the domain

[0x10f2c]

Troubleshooted this one and figured it out at least for my end.

The error is due to bad permissions on the file in the share, chmod 644 the dll and the error should go away; the group and others permissions need to be at least readable.

I am getting the same error on Windows Server 2019

[Woniuke]

you can use wireshark to analysis smb protocol for reason.


so the reason may not allow anonymous access....

I had this same issue when trying to run this against a sandbox Windows host which was the dev image Microsoft gives out. By default "User" does not have a password on that image.
When I set a password for the user I stopped getting this error. I tried a few things over time, so I can't promise that is the only fix, but it seems to have been what got everything functioning for me.

exploit worked on windows 10 2004 but after I updated it to 21H1 i am getting the same rpc error

Maybe you can try my code to build an anonymous SMB file server.

[muxueo]

也许你可以试试我的代码来构建一个匿名的 SMB 文件服务器。

Still not

Yes, what is the reason?
