The Puppet Communications Protocol in Puppet Enterprise 2015.3.x before 2015.3.3 does not properly validate certificates for the broker node, which allows remote non-whitelisted hosts to prevent runs from triggering via unspecified vectors.

The mcollective-puppet-agent plugin before 1.11.1 for Puppet allows remote attackers to execute arbitrary code via vectors involving the --server argument.

Puppet Labs Facter 1.6.0 through 2.4.0 allows local users to obtains sensitive Amazon EC2 IAM instance metadata by reading a fact for an Amazon EC2 node.

Untrusted search path vulnerability in Puppet Enterprise 2.8 before 2.8.7, Puppet before 2.7.26 and 3.x before 3.6.2, Facter 1.6.x and 2.x before 2.0.2, Hiera before 1.3.4, and Mcollective before 2.5.2, when running with Ruby 1.9.1 or earlier, allows local users to gain privileges via a Trojan horse file in the current working directory, as demonstrated using (1) rubygems/defaults/operating_system.rb, (2) Win32API.rb, (3) Win32API.so, (4) safe_yaml.rb, (5) safe_yaml/deep.rb, or (6) safe_yaml/deep.so; or (7) operatingsystem.rb, (8) operatingsystem.so, (9) osfamily.rb, or (10) osfamily.so in puppet/confine.

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.

The pe_mcollective module in Puppet Enterprise (PE) before 2.7.1 does not properly restrict access to a catalog of private SSL keys, which allows remote authenticated users to obtain sensitive information and gain privileges by leveraging root access to a node, related to the master role.

Multiple cross-site request forgery (CSRF) vulnerabilities in the (1) node request management, (2) live management, and (3) user administration components in the console in Puppet Enterprise (PE) before 2.7.1 allow remote attackers to hijack the authentication of unspecified victims via unknown vectors.

Puppet Enterprise (PE) before 2.6.1 does not properly invalidate sessions when the session secret has changed, which allows remote authenticated users to retain access via unspecified vectors.

Puppet before 3.3.3 and 3.4 before 3.4.1 and Puppet Enterprise (PE) before 2.8.4 and 3.1 before 3.1.1 allows local users to overwrite arbitrary files via a symlink attack on unspecified files.

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.
