Synopsis
========
A vulnerability was discovered in PHPUnit which may allow an
unauthenticated remote attacker to execute arbitrary PHP code.
Background
==========
PHPUnit is a programmer-oriented testing framework for PHP. It is an
instance of the xUnit architecture for unit testing frameworks.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-php/phpunit < 5.7.15-r1 >= 5.7.15-r1
Description
===========
When PHPUnit is installed in a production environment via composer and
these modules are in a web accessible directory, the eval-stdin.php
file in PHPUnit contains vulnerable statements that trigger the
vulnerability.
Impact
======
A remote attacker could possibly execute arbitrary PHP code or cause a
Denial of Service condition.
Workaround
==========
There are several ways to fix or mitigate this vulnerability:
Remove PHPUnit from the production environment.
Update PHPUnit.
Manually apply the patch.
Disable direct access to the composer packages by placing .htaccess
file to /vendor folder.
