AI-suggested
The primary mitigation is to upgrade all manyfold instances to version 0.133.0 or later, where the vulnerability is fixed. Until upgrade, organizations should disable the model render generation feature if feasible to reduce risk. Implement strict access controls to limit who can upload files, ensuring only trusted users have upload permissions. Employ network segmentation to isolate manyfold servers from critical infrastructure. Monitor logs for suspicious upload activity or command execution attempts. Use application-level firewalls or runtime application self-protection (RASP) tools to detect and block command injection patterns. Conduct regular audits of user accounts and enforce strong authentication mechanisms to reduce risk from compromised credentials. Additionally, consider sandboxing or containerizing manyfold instances to limit the blast radius of potential exploitation. Educate users about the risks of uploading untrusted files and maintain up-to-date backups to recover from potential attacks.
Description
Manyfold is an open source, self-hosted web application for managing a collection of 3d models, particularly focused on 3d printing. Prior to version 0.133.0, when model render generation is enabled, a logged-in user can achieve RCE by uploading a ZIP containing a file with a shell metacharacter in its name. The filename reaches a Ruby backtick call unsanitized. Version 0.133.0 fixes the issue.
