designsecurity/progpilot: A static analysis tool for security

A static application security testing (SAST) for PHP

There are many options available, select the one that best suits your use case.

• Download the latest PHAR archive from the releases page.
• Place the file somewhere in your path and make it executable:

chmod +x progpilot_vX.Y.Z.phar
sudo mv progpilot_vX.Y.Z.phar /usr/local/bin/progpilot

• Build the docker image (detailed documentation on this page) and run the container:

docker build -t progpilot .
docker run -v $(pwd):/workspace progpilot /workspace/path/to/your/file.php

phar-composer.phar should be located in a directory listed in the $PATH environment variable:

git clone https://github.com/designsecurity/progpilot
cd progpilot
./build.sh

The resulting phar archive will be located in the builds folder at the root of this project.

Install the package with composer, typically when using progpilot as a library of your PHP project:

composer require --dev designsecurity/progpilot

Use a yaml configuration file (look at this example) to configure and customize the progpilot analysis otherwise the default configuration will be used with, in particular the standard taint configuration data.

The progpilot command takes as arguments the path to the files and folders to be analyzed and optionally a configuration file:

# without config file
progpilot example1.php example2.php folder1/ folder2/
# with a config file
progpilot --configuration configuration.yml example1.php example2.php folder1/ folder2/

If you installed it with composer, the program will be located at vendor/bin/progpilot.

It is also possible to use progpilot inside PHP code. For more information look at the API documentation.

Use this code to analyze source_code1.php:

<?php
require_once './vendor/autoload.php';

$context = new \progpilot\Context;
$analyzer = new \progpilot\Analyzer;

$context->inputs->setFile("source_code1.php");

try {
  $analyzer->run($context);
} catch (Exception $e) {
   echo "Exception : ".$e->getMessage()."\n";
}  
  
$results = $context->outputs->getResults();

var_dump($results);

When source_code1.php contains this code:

<?php
$var7 = $_GET["p"];
$var4 = $var7;
echo "$var4";

The simplified output will be:

array(1) {
  [0]=>
  array(11) {
    ["source_name"]=>
    array(1) {
      [0]=>
      string(5) "$var4"
    }
    ["source_line"]=>
    array(1) {
      [0]=>
      int(4)
    }
    ["sink_name"]=>
    string(4) "echo"
    ["sink_line"]=>
    int(5)
    ["vuln_name"]=>
    string(3) "xss"
  }
}

All files (composer.json, example1.php, source_code1.php) used in this example are in the projects/example folder. For more examples look also at this page.

It is strongly recommended to customize the taint analysis configuration (the definitions of sinks, sources, sanitizers and validators) according to the context of the application to be analyzed. In the following specification, superglobals variables _GET, _POST or _COOKIE are defined as untrusted and also the return of the shell_exec() function:

{
    "sources": [
        {"name": "_GET", "is_array": true, "language": "php"},
        {"name": "_POST", "is_array": true, "language": "php"},
        {"name": "_COOKIE", "is_array": true, "language": "php"},
        {"name": "shell_exec", "is_function": true, "language": "php"}
    ]
}

See available settings in the corresponding chapter about specifying an analysis.
Custom rules can be created too, see the corresponding chapter about custom rules.
