Versions of Puppet Enterprise prior to 2016.4.5 or 2017.2.1 failed to mark MCollective server private keys as sensitive (a feature added in Puppet 4.6), so key values could be logged and stored in PuppetDB. These releases use the sensitive data type to ensure this won't happen anymore.

Open redirect vulnerability in the Console in Puppet Enterprise before 2015.2.1 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via the string parameter.

Puppet Enterprise before 3.7.1 allows remote authenticated users to obtain licensing and certificate signing request information by leveraging access to an unspecified API endpoint.

The MCollective aes_security plugin, as used in Puppet Enterprise before 3.3.0 and Mcollective before 2.5.3, does not properly validate new server certificates based on the CA certificate, which allows local users to establish unauthorized Mcollective connections via unspecified vectors related to a race condition.

Multiple cross-site request forgery (CSRF) vulnerabilities in Puppet Enterprise (PE) before 3.0.1 allow remote attackers to hijack the authentication of users for requests that deleting a (1) report, (2) group, or (3) class or possibly have other unspecified impact.

Puppet Enterprise before 3.2.0 does not properly restrict access to node endpoints in the console, which allows remote attackers to obtain sensitive information via unspecified vectors.

The master external node classification script in Puppet Enterprise before 3.2.0 does not verify the identity of consoles, which allows remote attackers to create arbitrary classifications on the master by spoofing a console.

Puppet Enterprise before 3.1.0 does not properly restrict the number of authentication attempts by a console account, which makes it easier for remote attackers to bypass intended access restrictions via a brute-force attack.

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

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 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 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 does not use a session timeout, which makes it easier for attackers to gain privileges by leveraging an unattended workstation.

Puppet Module Tool (PMT), as used in Puppet 2.7.x before 2.7.23 and 3.2.x before 3.2.4, and Puppet Enterprise 2.8.x before 2.8.3 and 3.0.x before 3.0.1, installs modules with weak permissions if those permissions were used when the modules were originally built, which might allow local users to read or modify those modules depending on the original permissions.

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 Enterprise before 3.0.1 does not sufficiently invalidate a session when a user logs out, which might allow remote attackers to hijack sessions by obtaining an old session ID.

Unspecified vulnerability in Puppet 2.7.x before 2.7.23 and 3.2.x before 3.2.4, and Puppet Enterprise 2.8.x before 2.8.3 and 3.0.x before 3.0.1, allows remote attackers to execute arbitrary Ruby programs from the master via the resource_type service. NOTE: this vulnerability can only be exploited utilizing unspecified "local file system access" to the Puppet Master.
