CVE-2022-0824Public exploitNetwork attack vector

Authenticated root command execution via foreign-module ACL bypass

Published Mar 2, 2022 · Updated Aug 2, 2024

Improper access control in Webmin before 1.990 allows remote authenticated users to execute commands with root privileges through File Manager. The Authentic theme invokes File Manager operations as a foreign module, while init_config skips module authorization unless FOREIGN_MODULE_SEC_CHECK is set. An untrusted Webmin account with File Manager access and no module restrictions can read root-owned files and reach command execution; Virtualmin domain owners are not affected.
