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 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 an authorized SSL key and certain permissions on the puppet master to read arbitrary files via a symlink attack in conjunction with a crafted REST request for a file in a filebucket.

Unspecified vulnerability in 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 to (1) cause a denial of service (memory consumption) via a REST request to a stream that triggers a thread block, as demonstrated using CVE-2012-1986 and /dev/random; or (2) cause a denial of service (filesystem consumption) via crafted REST requests that use "a marshaled form of a Puppet::FileBucket::File object" to write to arbitrary file locations.

Puppet 2.6.x before 2.6.14 and 2.7.x before 2.7.11, and Puppet Enterprise (PE) Users 1.0, 1.1, 1.2.x, 2.0.x before 2.0.3, when managing a user login file with the k5login resource type, allows local users to gain privileges via a symlink attack on .k5login.

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 uses predictable file names when installing Mac OS X packages from a remote source, which allows local users to overwrite arbitrary files or install arbitrary packages via a symlink attack on a temporary file in /tmp.

The change_user method in the SUIDManager (lib/puppet/util/suidmanager.rb) in Puppet 2.6.x before 2.6.14 and 2.7.x before 2.7.11, and Puppet Enterprise (PE) Users 1.0, 1.1, 1.2.x, 2.0.x before 2.0.3 does not properly manage group privileges, which allows local users to gain privileges via vectors related to (1) the change_user not dropping supplementary groups in certain conditions, (2) changes to the eguid without associated changes to the egid, or (3) the addition of the real gid to supplementary groups.

Puppet 2.6.x before 2.6.12 and 2.7.x before 2.7.6, and Puppet Enterprise (PE) Users 1.0, 1.1, and 1.2 before 1.2.4, when signing an agent certificate, adds the Puppet master's certdnsnames values to the X.509 Subject Alternative Name field of the certificate, which allows remote attackers to spoof a Puppet master via a man-in-the-middle (MITM) attack against an agent that uses an alternate DNS name for the master, aka "AltNames Vulnerability."

Directory traversal vulnerability in Puppet 2.6.x before 2.6.10 and 2.7.x before 2.7.4 allows remote attackers to write X.509 Certificate Signing Request (CSR) to arbitrary locations via (1) a double-encoded key parameter in the URI in 2.7.x, (2) the CN in the Subject of a CSR in 2.6 and 0.25.

Puppet 2.7.x before 2.7.5, 2.6.x before 2.6.11, and 0.25.x allows local users to overwrite arbitrary files via a symlink attack on the .k5login file.
