VU#456950: Komodo Periphery Agent Contains an OS Command Injection Vulnerability

Overview Versions <= 2.2.0 of Periphery, an agent within the Komodo server management platform, is vulnerable to OS command injection due to missing validation of container names, through two vectors: container destruction and container log searches. This allows an authenticated attacker to execute arbitrary commands as root on the underlying host, enabling persistent compromise of infrastructure. Description Komodo is an open-source server and deployment manager, maintained by mogh.tech, widely used in self-hosted and Docker multi-server environments. Periphery is an agent service installed on servers to give Komodo control over Docker environments. In vulnerable versions of Komodo, Periphery does not properly validate user-supplied Docker container names before those values are interpolated into shell commands used by the agent. Two operations exhibit this vulnerability: container destruction (DestroyContainer / RemoveContainer) and container log searches (SearchContainerLog / GetContainerLogSearch). Through both avenues, raw container names are directly inserted into sh -c command lines without any shell escaping or validation. These commands then run with Periphery's root privileges on the host OS and Docker socket. Impact An authenticated non-admin user can escalate privileges through OS command injection via a maliciously crafted container name. Successful exploitation enables arbitrary command execution as root on a target server within a Komodo deployment. Ultimately, this enables an attacker to establish persistence, achieve lateral movement, and completely compromise a user or organization's managed infrastructure. Solution Fortunately, Komodo was reached to coordinate this vulnerability, and a patch has been implemented to remediate the issue in versions 2.3.0 and higher. The CERT/CC recommends that all users update immediately. Acknowledgements Thanks to Muhammadjon Ahmadjonov for reporting this vulnerability. This document was written by Alex Lewis.
