How the Exploit Works
The vulnerability stems from the overly-permissive filesystem permissions associated with Docker containers in Vasion Print Virtual Appliance Host and Application. The software mounts host configuration and secret material under /var/www/efs_storage into numerous Docker containers. Consequently, files such as secrets.env, GPG-encrypted blobs in .secrets, MySQL client keys, and application session files become accessible from multiple containers.
If an attacker gains control over or access to any of these containers, they can read or modify these artifacts. This could lead to credential theft, Remote Code Execution (RCE) via Laravel APP_KEY, Portainer takeover, and ultimately a full compromise of the system.
Conceptual Example Code
This is a conceptual example of how an attacker might attempt to exploit this vulnerability.
# Command to list files in the Docker container
docker exec -it [container_id] ls /var/www/efs_storage
# Command to read sensitive files
docker exec -it [container_id] cat /var/www/efs_storage/secrets.envIn the above example, the attacker uses Docker commands to list and read sensitive files in the Docker container. This is a simplified representation and actual exploitation may involve more complex commands and manipulations.
Mitigation Guidance
To mitigate this vulnerability, it is recommended that organizations apply the vendor’s patch immediately. If this is not immediately possible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as temporary mitigation. However, these measures do not eliminate the vulnerability, and the patch should still be applied as soon as it becomes feasible.
Remember, staying vigilant and keeping systems up-to-date is an essential part of maintaining a strong cybersecurity posture.
