CVE-2017-2295
8.2 · HIGHOverview
CVE-2017-2295 is a high-severity vulnerability affecting puppet puppet. It was published on July 5, 2017 and has a CVSS 3.0 base score of 8.2 (HIGH).
This vulnerability has a CVSS 3.0 base score of 8.2, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from puppet. Update puppet to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
