CVE-2022-36446Public exploitNetwork attack vector

Authenticated OS command execution via de-escaped package name

Published Jul 25, 2022 · Updated Aug 3, 2024

Command injection in Webmin before 1.997 allows remote authenticated users to execute arbitrary OS commands through a crafted package name. In software/apt-lib.pl, update_system_install removes backslashes added by quotemeta before concatenating the package value into the package-manager command, restoring shell metacharacters. Exploitation requires an account permitted to access Software Package Updates, and commands run with Webmin's server privileges.
