Previous versions of Puppet Agent didn't verify the peer in the SSL connection prior to downloading the CRL. This issue is resolved in Puppet Agent 6.4.0.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-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-2020-7943debianpuppetdb+5EPSS score7.67%
Puppet Server and PuppetDB provide useful performance and debugging information via their metrics API endpoints. For PuppetDB this may contain things like hostnames. Puppet Server reports resource names and titles for defined types (which may contain sensitive information) as well as function names and class names. Previously, these endpoints were open to the local network. PE 2018.1.13 & 2019.5.0, Puppet Server 6.9.2 & 5.3.12, and PuppetDB 6.9.1 & 5.2.13 disable trapperkeeper-metrics /v1 metrics API and only allows /v2 access on localhost by default. This affects software versions: Puppet Enterprise 2018.1.x stream prior to 2018.1.13 Puppet Enterprise prior to 2019.5.0 Puppet Server prior to 6.9.2 Puppet Server prior to 5.3.12 PuppetDB prior to 6.9.1 PuppetDB prior to 5.2.13 Resolved in: Puppet Enterprise 2018.1.13 Puppet Enterprise 2019.5.0 Puppet Server 6.9.2 Puppet Server 5.3.12 PuppetDB 6.9.1 PuppetDB 5.2.13CVE-2014-7170puppetpuppet_serverEPSS score0.23%
Race condition in Puppet Server 0.2.0 allows local users to obtain sensitive information by accessing it in between package installation or upgrade and the start of the service.CVE-2017-2295debianpuppet+10EPSS score2.38%
Versions of Puppet prior to 4.10.1 will deserialize data off the wire (from the agent to the server, in this case) with a attacker-specified format. This could be used to force YAML deserialization in an unsafe manner, which would lead to remote code execution. This change constrains the format of data on the wire to PSON or safely decoded YAML.CVE-2023-1894debianpuppetserver+4EPSS score0.44%
A Regular Expression Denial of Service (ReDoS) issue was discovered in Puppet Server 7.9.2 certificate validation. An issue related to specifically crafted certificate names significantly slowed down server operations.CVE-2023-5255ubuntupuppet+2EPSS score0.48%
For certificates that utilize the auto-renew feature in Puppet Server, a flaw exists which prevents the certificates from being revoked.
