[Bug] powershell encoded command fails
Bug
Describe the feature request or bug The encoded command for the powershell launcher fails to execute.
To Reproduce Steps to reproduce the behavior:
- create powershell launcher
- copy encoded command output
- paste command into windows terminal
Expected behavior target connects to Covenant
Screenshots no screen shots available
Covenant Server Information:
- OS: kali and windows
- Docker or Native: Native
Browser Information:
- Browser firefox and brave
- Version 78.11.0esr and 1.27.109
Target Information (System that implant is running on):
- OS: windows
- Version server 2019 standard
Additional context I get the standard powershell output that echoes to the screen when you enter in a command incorrectly. Exact verbiage at the top is: "cannot process the command because the value specified with -EncodedCommand is not properly encoded. The value must be Base64 encoded."
I RDP'd directly into the target server and tried to use the -encodedcommand in the standard windows terminal; but it appears that it is being truncated. I noticed the same issue in [Bug] Powershell launcher fails #330; but RDPing in and pasting the command resolved the issue. This encoded command is too large to paste into the terminal though and saving it as a bat file writes to disk and triggers AV.
If you're RDPing there's a good chance it will get cut off - try hosting the file instead via launcher->powershell->host panel
My RDP was giving me this error:
[14:48:12:256] [825884:825935] [WARN][com.freerdp.client.x11] - failed to get clipboard data in format UTF8_STRING [source format CF_UNICODETEXT]
