AI-suggested
- Upgrade manyfold to version 0.133.0 or later, which contains the fix for this vulnerability.
- Review and configure all proxy caches and reverse proxies in front of manyfold to ensure that session cookies are not cached. This includes setting appropriate Cache-Control headers such as 'no-store' and 'private' on responses containing authentication cookies.
- Implement secure cookie attributes like 'HttpOnly', 'Secure', and 'SameSite' to reduce cookie leakage risks.
- Enforce short session lifetimes and implement session invalidation on logout or inactivity to minimize the window of opportunity for session hijacking.
- Monitor access logs for unusual access patterns that may indicate session hijacking attempts.
- Educate users about the risks of interacting with untrusted networks or proxies that may cache sensitive information.
- Consider deploying Web Application Firewalls (WAFs) that can detect and block suspicious session-related activities.
- Conduct regular security assessments and penetration tests focusing on session management and proxy configurations.
Description
Manyfold is an open source, self-hosted web application for managing a collection of 3d models, particularly focused on 3d printing. Versions prior to 0.133.0 are vulnerable to session hijack via cookie leakage in proxy caches. Version 0.133.0 fixes the issue.
