CVE-2012-3866

13
FAUCET Score

CVE-2012-3866 describes an information disclosure vulnerability in Puppet 2.7.x before 2.7.18 and Puppet Enterprise before 2.5.2. The vulnerability arises because the last_run_report.yaml file is created with overly permissive 0644 permissions, allowing local users with access to the Puppet master server to read sensitive configuration data. With a CVSS score of 2.1 (AV:L/AC:L/Au:N/C:P/I:N/A:N), this is a low-severity vulnerability requiring local access for exploitation, leading only to confidentiality impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
