Description

secunia reports :

Stefan Esser has reported a vulnerability in Piwik, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to the core/Cookie.php script using 'unserialize()' with user controlled input. This can be exploited to e.g. execute arbitrary PHP code via the 'wakeup()' or 'destruct()' methods of a serialized object passed via an HTTP cookie.
