Overview
Vasion Print, formerly known as PrinterLogic, is a printing solution that both small businesses and large enterprises heavily rely on. A recently discovered vulnerability, CVE-2025-34204, poses a significant security risk to these businesses. This vulnerability, found in the Vasion Print Virtual Appliance Host and Application, allows potential attackers to gain root access to the Docker containers running primary application processes, thereby significantly increasing the blast radius of a container compromise.
The implications of this vulnerability are grave. A breach could allow for lateral movement inside the network and even potentially compromise the host system, leading to a complete system takeover or data leak. As such, it’s crucial for organizations using Vasion Print to take immediate action to mitigate this security risk.

How the Exploit Works
The vulnerability stems from the fact that the Docker containers in Vasion Print’s Virtual Appliance Host and Application run their primary application processes, such as PHP workers, Node.js servers, and custom binaries, as the root user. A potential attacker who manages to breach a single Docker container could thus gain root access to it.
Once inside, the attacker is free to move laterally within the compromised container and potentially exploit the host system. The security risk arises because many Docker containers share the same operating system kernel as the host, allowing the attacker to escalate privileges on the host system and potentially compromise it.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited. Please note that this is a simplified representation and the actual attack may involve more intricate steps.
# After breaching the Docker container
$ whoami
> root
# Attempt to write to a system file
$ echo "malicious code" >> /etc/critical_system_fileIn this example, the attacker has breached the Docker container and confirmed that they have root access. They then attempt to write to a critical system file, which should be restricted. However, because of the vulnerability, the write operation succeeds, potentially leading to a system compromise.
Mitigation Guidance
To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. Until then, deploying a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) may provide temporary mitigation. Regular monitoring of system logs and network traffic for any unusual activity can also help detect a potential exploit early.
