Summary
by MITRE • 07/30/2026
The Boot Dashboard Docker integration in Spring Tools publishes container control ports on all of the host's network interfaces (0.0.0.0) rather than restricting them to loopback. Affected Spring Products and Versions: Spring Tools for Eclipse: 5.2.0 and earlier

The vulnerability in Spring Tools for Eclipse affects the Boot Dashboard Docker integration functionality where container control ports are inadvertently exposed on all network interfaces instead of being restricted to localhost only. This configuration flaw creates a significant security risk by allowing unauthorized access to container management interfaces from external networks. The issue specifically impacts versions 5.2.0 and earlier, where the Docker integration component fails to properly bind container control endpoints to loopback addresses, thereby exposing administrative functions to potential attackers who might be able to manipulate or compromise running containers through these exposed ports.
This technical flaw represents a classic misconfiguration vulnerability that aligns with CWE-668, which describes insufficient control of a resource through multiple interfaces. The improper binding of network services to all interfaces rather than localhost creates an attack surface that violates fundamental security principles of least privilege and network segmentation. When container control ports are published on 0.0.0.0, any system with network access to the host can potentially interact with running containers through these exposed management endpoints, creating opportunities for privilege escalation, data compromise, or container-based attacks.
The operational impact of this vulnerability extends beyond simple network exposure as it enables attackers to potentially gain unauthorized control over containerized applications and services. An attacker who discovers these exposed ports could perform various malicious activities including but not limited to executing commands within containers, accessing sensitive container data, modifying container configurations, or using the compromised containers as launch points for further attacks on the broader network infrastructure. The vulnerability particularly affects development environments where Spring Tools is used for container management, making it a significant concern for developers working with Docker integration in their local development setups.
Organizations should implement immediate mitigations by upgrading to Spring Tools versions that address this vulnerability, specifically version 5.2.1 or later where the Docker integration has been corrected to bind control ports to loopback interfaces only. Additionally, network administrators should consider implementing firewall rules and network segmentation policies to restrict access to development hosts running affected versions of Spring Tools. The remediation approach should align with ATT&CK technique T1071.004 for application layer protocol usage and T1566 for credential access through network services. Security teams should also conduct regular vulnerability assessments to identify similar misconfigurations in other development tools and container management systems within their infrastructure, as this type of exposure commonly occurs in development environments where security hardening is often overlooked due to the perceived trust level of local development machines.
