Alta

VetorAV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N
Name of the Vulnerable Software and Affected Versions Puppet versions prior to 4.10.1
Description The issue allows an attacker to force YAML deserialization in an unsafe manner, potentially leading to remote code execution. This is due to the deserialization of data from the agent to the server without proper format constraints.
Recommendations For versions prior to 4.10.1, update to version 4.10.1 or later to constrain the format of data on the wire to PSON or safely decoded YAML, preventing unsafe YAML deserialization.
