CVE-2012-1989: n/a vulnerability

CVE-2012-1989: telnet.rb in Puppet 2.7.x before 2.7.13 and Puppet Enterprise (PE) 1.2.x, 2.0.x, and 2.5.x before 2.5.1 all...

telnet.rb in Puppet 2.7.x before 2.7.13 and Puppet Enterprise (PE) 1.2.x, 2.0.x, and 2.5.x before 2.5.1 allows local users to overwrite arbitrary files via a symlink attack on the NET::Telnet connection log (/tmp/out.log).

Security readout for executives and security teams

This is an old local file-overwrite flaw in Puppet. A local user on a system running affected Puppet or Puppet Enterprise versions could abuse a temporary Telnet log path to overwrite files. The business risk is concentrated in legacy configuration-management hosts with local user access. Likely exposure is limited to organizations still running the affected 2012-era Puppet or Puppet Enterprise branches. Systems without local untrusted users, or systems already upgraded beyond the listed fixed versions, are less likely to be exposed. Treat this as a legacy-platform hygiene issue unless vulnerable Puppet hosts still exist with local user access. Prioritize remediation on configuration-management servers or privileged automation hosts because file overwrite flaws can affect system integrity. Mitigation focus: Upgrade Puppet 2.7.x to 2.7.13 or later.; Upgrade Puppet Enterprise 2.5.x to 2.5.1 or later.; Review vendor advisories before applying changes to legacy deployments..
