Puppet Agent 1.10.x prior to 1.10.13, Puppet Agent 5.3.x prior to 5.3.7, and Puppet Agent 5.5.x prior to 5.5.2 on Windows only, with a specially crafted configuration file an attacker could get pxp-agent to load arbitrary code with privilege escalation.CVE-2018-6514puppetpuppet+1EPSS score0.85%
In Puppet Agent 1.10.x prior to 1.10.13, Puppet Agent 5.3.x prior to 5.3.7, Puppet Agent 5.5.x prior to 5.5.2, Facter on Windows is vulnerable to a DLL preloading attack, which could lead to a privilege escalation.CVE-2021-27023debianpuppet+10EPSS score1.37%
A flaw was discovered in Puppet Agent and Puppet Server that may result in a leak of HTTP credentials when following HTTP redirects to a different host. This is similar to CVE-2018-1000007CVE-2021-27025debianpuppet+9EPSS score1.11%
A flaw was discovered in Puppet Agent where the agent may silently ignore Augeas settings or may be vulnerable to a Denial of Service condition prior to the first 'pluginsync'.CVE-2015-1855debianruby1.8+11EPSS score2.81%
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.CVE-2016-2786puppetpuppet_agent+1EPSS score1.56%
The pxp-agent component in Puppet Enterprise 2015.3.x before 2015.3.3 and Puppet Agent 1.3.x before 1.3.6 does not properly validate server certificates, which might allow remote attackers to spoof brokers and execute arbitrary commands via a crafted certificate.CVE-2016-2785RubyGemspuppet+3EPSS score2.89%
Puppet Server before 2.3.2 and Ruby puppetmaster in Puppet 4.x before 4.4.2 and in Puppet Agent before 1.4.2 might allow remote attackers to bypass intended auth.conf access restrictions by leveraging incorrect URL decoding.CVE-2016-5713debianpuppet+1EPSS score2.02%
Versions of Puppet Agent prior to 1.6.0 included a version of the Puppet Execution Protocol (PXP) agent that passed environment variables through to Puppet runs. This could allow unauthorized code to be loaded. This bug was first introduced in Puppet Agent 1.3.0.CVE-2016-5714debianpuppet+2EPSS score2.24%
Puppet Enterprise 2015.3.3 and 2016.x before 2016.4.0, and Puppet Agent 1.3.6 through 1.7.0 allow remote attackers to bypass a host whitelist protection mechanism and execute arbitrary code on Puppet nodes via vectors related to command validation, aka "Puppet Execution Protocol (PXP) Command Whitelist Validation Vulnerability."CVE-2020-7942debianpuppet+4EPSS score0.80%
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 5.5.19CVE-2017-10690ubuntupuppet+4EPSS score1.00%
In previous versions of Puppet Agent it was possible for the agent to retrieve facts from an environment that it was not classified to retrieve from. This was resolved in Puppet Agent 5.3.4, included in Puppet Enterprise 2017.3.4CVE-2017-10689canonicalubuntu_linux+13EPSS score0.36%
In previous versions of Puppet Agent it was possible to install a module with world writable permissions. Puppet Agent 5.3.4 and 1.10.10 included a fix to this vulnerability.
