Synopsis

phpDocumentor bundles Smarty which contains an input sanitation flaw, allowing attackers to call arbitrary PHP functions.

2. Impact Information

Background

The phpDocumentor package provides automatic documenting of PHP API directly from the source.

Impact

A remote attacker could call arbitrary PHP functions via templates.
