Aliases Command Parsing - Issue with whitespaces

[PhilippRieth]

Describe the bug
Spaces in arguments parsed as part of execute-assembly don't seem to be parsed correctly.

To Reproduce
(SharpPersis.exe is just an example, same issue with other assemblies)

Steps to reproduce the behavior:

• Parse argument with spaces to execute-assembly
• Spaces in argument 'My Scheduled Task' do not get parsed properly

sliver (MINIMAL_BIKE) > execute-assembly -i -M /home/user/tools/SharPersist.exe '' -t schtask -m add -a logon -n \"My Scheduled Task\" -c \"C:\\Program Files (x86)\\Program1\\implant.exe\"

[...SharpPersist error here due to the spaces in 'My Scheduled Task'...]

• What works:

sliver (MINIMAL_BIKE) > execute-assembly -i -M /home/user/tools/SharPersist.exe '' -t schtask -m add -a logon -n \" MyScheduledTask\" -c \"C:\\Program Files (x86)\\Program1\\implant.exe\"
[*] Output:

[*] INFO: Adding scheduled task persistence
[*] INFO: Command: "C:\Program
[*] INFO: Command Args: logon
[*] INFO: Scheduled Task Name: "MyScheduledTask"
[*] INFO: Option:

the MethodInfo::Invoke_3 method returned an error:
The specified resource type cannot be found in the image file.

• Still, you can see in line [*] INFO: Command: "C:\Program that it did not like the space in "C:\\Program Files (x86)\\Program1\\implant.exe"
• I tried all sorts of things (Aliases and Extensions | sliver.sh) and can't seem to get the space parsed correctly.

Expected behavior

• Being able to parse spaces in arguments while using execute-assembly

Sliver Version

• Server v1.5.42

I used a path that does not contain spaces and still couldn't create a scheduled task. Are you able to create it without spaces?

That's a bug. I fixed it in v1.6 but there has not been a backport to v1.5-master yet.
