Description

An arbitrary code execution vulnerability has been reported in the TFTP module, where the variant part of the URL (/tftp/<variant>/<MAC>) is passed into eval().

https://github.com/theforeman/smart-proxy/blob/1.11.1/modules/tftp/tftp_api.rb#L17

Mitigation: ensure trusted_hosts is set to only authorise Foreman hosts to use the API, and preferably only use HTTPS for better authentication.

Affects Smart Proxy 0.2 or higher.

Thanks to Lukas Zapletal for reporting to , a CVE will be assigned shortly.
