Puppet: Security Vulnerabilities
Puppet Server and PuppetDB provide useful performance and debugging information via their metrics API endpoints. For PuppetDB this may contain things like hostnames. Puppet Server reports resource names and titles for defined types (which may contain sensitive information) as well as function names and class names. Previously, these endpoints were open to the local network. PE 2018.1.13 & 2019.5.0, Puppet Server 6.9.2 & 5.3.12, and PuppetDB 6.9.1 & 5.2.13 disable trapperkeeper-metrics /v1 metrics API and only allows /v2 access on localhost by default. This affects software versions: Puppet Enterprise 2018.1.x stream prior to 2018.1.13 Puppet Enterprise prior to 2019.5.0 Puppet Server prior to 6.9.2 Puppet Server prior to 5.3.12 PuppetDB prior to 6.9.1 PuppetDB prior to 5.2.13 Resolved in: Puppet Enterprise 2018.1.13 Puppet Enterprise 2019.5.0 Puppet Server 6.9.2 Puppet Server 5.3.12 PuppetDB 6.9.1 PuppetDB 5.2.13

Parts of the Puppet Enterprise Console 3.x were found to be susceptible to clickjacking and CSRF (Cross-Site Request Forgery) attacks. This would allow an attacker to redirect user input to an untrusted site or hijack a user session.

Previously, Puppet operated on a model that a node with a valid certificate was entitled to all information in the system and that a compromised certificate allowed access to everything in the infrastructure. When a node's catalog falls back to the `default` node, the catalog can be retrieved for a different node by modifying facts for the Puppet run. This issue can be mitigated by setting `strict_hostname_checking = true` in `puppet.conf` on your Puppet master. Puppet 6.13.0 and 5.5.19 changes the default behavior for strict_hostname_checking from false to true. It is recommended that Puppet Open Source and Puppet Enterprise users that are not upgrading still set strict_hostname_checking to true to ensure secure behavior. Affected software versions: Puppet 6.x prior to 6.13.0 Puppet Agent 6.x prior to 6.13.0 Puppet 5.5.x prior to 5.5.19 Puppet Agent 5.5.x prior to 5.5.19 Resolved in: Puppet 6.13.0 Puppet Agent 6.13.0 Puppet 5.5.19 Puppet Agent 5.5.19

Previous versions of Puppet Agent didn't verify the peer in the SSL connection prior to downloading the CRL. This issue is resolved in Puppet Agent 6.4.0.

The express install, which is the suggested way to install Puppet Enterprise, gives the user a URL at the end of the install to set the admin password. If they do not use that URL, there is an overlooked default password for the admin user. This was resolved in Puppet Enterprise 2019.0.3 and 2018.1.9.

When using the cd4pe::root_configuration task to configure a Continuous Delivery for PE installation, the root user’s username and password were exposed in the job’s Job Details pane in the PE console. These issues have been resolved in version 1.2.1 of the puppetlabs/cd4pe module.

Puppet Enterprise before 3.0.1 allows remote attackers to (1) conduct clickjacking attacks via unspecified vectors related to the console, and (2) conduct cross-site scripting (XSS) attacks via unspecified vectors related to "live management."

verify_certificate_identity in the OpenSSL extension in Ruby before 2.0.0 patchlevel 645, 2.1.x before 2.1.6, and 2.2.x before 2.2.2 does not properly validate hostnames, which allows remote attackers to spoof servers via vectors related to (1) multiple wildcards, (1) wildcards in IDNA names, (3) case sensitivity, and (4) non-ASCII characters.

Prior to version 0.3.0, chloride's use of net-ssh resulted in host fingerprints for previously unknown hosts getting added to the user's known_hosts file without confirmation. In version 0.3.0 this is updated so that the user's known_hosts file is not updated by chloride.
