Puppet Enterprise before 3.0.1 uses HTTP responses that contain sensitive information without the "no-cache" setting, which might allow local users to obtain sensitive information such as (1) host name, (2) MAC address, and (3) SSH keys via the web browser cache.

Puppet Enterprise before 3.0.1 allows remote attackers to obtain the database password via vectors related to how the password is "seeded as a console parameter," External Node Classifiers, and the lack of access control for /nodes.

Puppet Enterprise before 3.0.1 does not set the secure flag for the session cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.

The reset password page in Puppet Enterprise before 3.0.1 does not force entry of the current password, which allows attackers to modify user passwords by leveraging session hijacking, an unattended workstation, or other vectors.

Puppet 2.7.x before 2.7.22 and 3.2.x before 3.2.2, and Puppet Enterprise before 2.8.2, deserializes untrusted YAML, which allows remote attackers to instantiate arbitrary Ruby classes and execute arbitrary code via a crafted REST API call.
