CVE-2022-30708Public exploitNetwork attack vector

Root command execution via unrestricted file parameter

Published May 15, 2022 · Updated Aug 3, 2024

Remote code execution in Webmin 1.991 and earlier allows remote authenticated users to execute commands with root privileges. Authentic theme's settings-editor_write.cgi accepts the file parameter without restricting its path, letting a low-privileged account overwrite root-owned scripts with attacker-supplied Perl. The route is exposed when Authentic theme is active and the account was manually created rather than provisioned through Virtualmin or Cloudmin.
