Parse: A PHP Security Scanner

The Parse scanner is a static scanning tool to review your PHP code for potential security-related issues. A static scanner means that the code is not executed and tested via a web interface (that’s dynamic testing). Instead, the scanner looks through your code and checks for certain markers and notifies you when any are found.

For example, you really shouldn’t be using eval in your code anywhere if you can help it. When the scanner runs, it will parse down each of your files and look for any eval() calls. If it finds any, it adds that match to the file and reports it in the results.

Installation

Install as a development dependency in your project using composer:

composer require --dev psecio/parse

The path to the installed executable may vary depending on your bin-dir setting. With the default, value parse is located at vendor/bin/psecio-parse.

For a system-wide installation use:

composer global require psecio/parse

Make sure you have ~/.composer/vendor/bin/ in your path.

The Checks

Here’s the current list of checks:

• Warn when sensitive values are committed (as defined by a variable like “username” set to a string)
• Warn when display_errors is enabled manually
• Avoid the use of eval()
• Avoid the use of exit or die()
• Avoid the use of logical operators (ex. using and over &&)
• Avoid the use of the ereg* functions (now deprecated)
• Ensure that the second parameter of extract is set to not overwrite (not EXTR_OVERWRITE)
• Checking output methods (echo, print, printf, print_r, vprintf, sprintf) that use variables in their options
• Ensuring you’re not using echo with file_get_contents
• Testing for the system execution functions and shell exec (backticks)
• Use of readfile, readlink and readgzfile
• Using parse_str or mb_parse_str (writes values to the local scope)
• Warn if a .phps file is found
• Using session_regenerate_id either without a parameter or using false
• Avoid use of $_REQUEST (know where your data is coming from)
• Don’t use mysql_real_escape_string
• Avoiding use of import_request_variables
• Avoid use of $GLOBALS
• Ensure the use of type checking validating against booleans (===)
• Ensure that the /e modifier isn’t used in regular expressions (execute)
• Using concatenation in header() calls
• Avoiding the use of $http_raw_post_data

Usage

To use the scanner execute it from the command line:

psecio-parse scan /path/to/my/project
