puppet: authenticated clients allowed to delete arbitrary files on the puppet master

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.

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.

puppet: insufficient validation of agent names in CN of SSL certificate requests

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.

puppet: possible host impersonation when using certificates issues for IP address

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: Puppet uses predictable filenames, allowing arbitrary file overwrite

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.

puppet: Filebucket arbitrary file read

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.

puppet: Insecure temporary file use for NET::Telnet connection log (/tmp/out.log)

telnet.rb in Puppet 2.7.x before 2.7.13 and Puppet Enterprise (PE) 1.2.x, 2.0.x, and 2.5.x before 2.5.1 allows local users to overwrite arbitrary files via a symlink attack on the NET::Telnet connection log (/tmp/out.log).

Puppet 2.6.13 group ID handling issues

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 2.6.13 Klogin File Handling Issue

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: Directory traversal attack by processing certain x509 certificate signing requests

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: K5login content attack

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.

puppet: SSH authorized_keys symlink attack

Puppet 2.7.x before 2.7.5, 2.6.x before 2.6.11, and 0.25.x allows local users to modify the permissions of arbitrary files via a symlink attack on the SSH authorized_keys file.

puppet: predictable temporary file using RAL

Puppet 2.7.x before 2.7.5, 2.6.x before 2.6.11, and 0.25.x, when running in --edit mode, uses a predictable file name, which allows local users to run arbitrary Puppet code or trick a user into editing arbitrary files.

puppet: MITM by the x509v3 certificate signing

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."
