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.

The dashboard report in Puppet Enterprise before 3.0.1 allows attackers to execute arbitrary YAML code via a crafted report-specific type.

Open redirect vulnerability in the login page in Puppet Enterprise before 3.0.1 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the service parameter.

Puppet Labs Puppet Enterprise before 2.8.0 does not use a "randomized secret" in the CAS client config file (casclientconfig.yml) when upgrading from older 1.2.x or 2.0.x versions, which allows remote attackers to obtain console access via a crafted cookie.

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 includes version information for the Apache and Phusion Passenger products in its HTTP response headers, which allows remote attackers to obtain sensitive information.

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.
