Snuffleupagus is a [PHP 7+](https://secure.php.net/) module designed to

drastically raise the cost of attacks against websites, by killing entire bug

classes. It also provides a powerful virtual-patching system, allowing

administrator to fix specific vulnerabilities and audit suspicious behaviours

without having to touch the PHP code.

## Key Features

* Close to zero performance impact

* Powerful yet simple to write virtual-patching rules

* Killing several classes of vulnerabilities

	* [Unserialize-based](https://www.owasp.org/images/9/9e/Utilizing-Code-Reuse-Or-Return-Oriented-Programming-In-PHP-Application-Exploits.pdf) code execution

	* [`mail`-based]( https://blog.ripstech.com/2016/roundcube-command-execution-via-email/ ) code execution

	* Cookie-stealing [XSS]( https://en.wikipedia.org/wiki/Cross-site_scripting )

	* File-upload based code execution

	* Weak PRNG

	* [XXE]( https://en.wikipedia.org/wiki/XML_external_entity_attack )

* Hardening features

	* Automatic `secure` and `samesite` flag for cookies

	* Bundled set of rules to detect post-compromissions behaviours

	* Global [strict mode]( https://secure.php.net/manual/en/migration70.new-features.php#migration70.new-features.scalar-type-declarations) and type-juggling prevention

	* Whitelisting of [stream wrappers](https://secure.php.net/manual/en/intro.stream.php)

	* Preventing writeable files execution

	* Whitelist/blacklist for `eval`

	* Request dumping capability

## Download

We've got a [download

page](https://snuffleupagus.readthedocs.io/download.html), where you can find

packages for your distribution, but you can of course just `git clone` this

repo, or check the releases on [github](https://github.com/nbs-system/snuffleupagus/releases).

## Examples

We're providing [various example rules](https://github.com/nbs-system/snuffleupagus/tree/master/config),

that are looking like this:

```python

# Harden the `chmod` function

sp.disable_function.function("chmod").param("mode").value_r("^[0-9]{2}[67]$").drop();

# Mitigate command injection in `system`

sp.disable_function.function("system").param("command").value_r("[$|;&`\\n]").drop();

```

Upon violation of a rule, you should see lines like this in your logs:

```python

[snuffleupagus][0.0.0.0][disabled_function][drop] The execution has been aborted in /var/www/index.php:2, because the return value (0) of the function 'strpos' matched a rule.

```

## Documentation

We've got a [comprehensive website](https://snuffleupagus.readthedocs.io/) with

all the documentation that you could possibly wish for. You can of course

[build it yourself](https://github.com/nbs-system/snuffleupagus/tree/master/doc).
