The (1) template and (2) inline_template functions in the master server in Puppet before 2.6.18, 2.7.x before 2.7.21, and 3.1.x before 3.1.1, and Puppet Enterprise before 1.2.7 and 2.7.x before 2.7.2 allows remote authenticated users to execute arbitrary code via a crafted catalog request.

lib/puppet/ssl/certificate_authority.rb in Puppet before 2.6.17 and 2.7.x before 2.7.18, and Puppet Enterprise before 2.5.2, does not properly restrict the characters in the Common Name field of a Certificate Signing Request (CSR), which makes it easier for user-assisted remote attackers to trick administrators into signing a crafted agent certificate via ANSI control sequences.

lib/puppet/defaults.rb in Puppet 2.7.x before 2.7.18, and Puppet Enterprise before 2.5.2, uses 0644 permissions for last_run_report.yaml, which allows local users to obtain sensitive configuration information by leveraging access to the puppet master server to read this file.

Directory traversal vulnerability in lib/puppet/reports/store.rb in Puppet before 2.6.17 and 2.7.x before 2.7.18, and Puppet Enterprise before 2.5.2, when Delete is enabled in auth.conf, allows remote authenticated users to delete arbitrary files on the puppet master server via a .. (dot dot) in a node name.

Puppet before 2.6.17 and 2.7.x before 2.7.18, and Puppet Enterprise before 2.5.2, allows remote authenticated users to read arbitrary files on the puppet master server by leveraging an arbitrary user's certificate and private key in a GET request.

lib/puppet/network/authstore.rb in Puppet before 2.7.18, and Puppet Enterprise before 2.5.2, supports use of IP addresses in certnames without warning of potential risks, which might allow remote attackers to spoof an agent by acquiring a previously used IP address.

Puppet 2.6.x before 2.6.15 and 2.7.x before 2.7.13, and Puppet Enterprise (PE) Users 1.0, 1.1, 1.2.x, 2.0.x, and 2.5.x before 2.5.1 allows remote authenticated users with agent SSL keys and file-creation permissions on the puppet master to execute arbitrary commands by creating a file whose full pathname contains shell metacharacters, then performing a filebucket request.
