CVE-2026-47882

Spring · Spring Tools for Eclipse

Spring Tools for Eclipse uses a cryptographically weak pseudo-random number generator to create shared secrets for remote-restart authentication, allowing potential unauthorized access.

Executive summary

A cryptographically weak secret generation flaw in Spring Tools for Eclipse allows potential unauthorized remote-restart uploads, posing a critical security risk to development environments.

Vulnerability

This vulnerability involves the use of a cryptographically weak pseudo-random number generator (CWE-338) when generating shared secrets for DevTools remote-restart functionality. The flaw allows an attacker with network access to potentially predict the secret, bypassing authentication requirements for remote application management.

Business impact

Successful exploitation of this vulnerability could lead to unauthorized control over remote application targets, including those running in Docker or Cloud Foundry. Given the CVSS score of 8.3, this high-severity flaw threatens the integrity and availability of development and staging infrastructure, potentially facilitating code injection or unauthorized system restarts.

Remediation

Immediate Action: Review the official Spring security advisory for available patches and apply them to all affected instances of Spring Tools for Eclipse immediately.

Proactive Monitoring: Monitor network traffic for unusual DevTools remote-restart upload patterns or unauthorized connection attempts to the application management port.

Compensating Controls: Restrict network access to management interfaces using firewalls or VPNs to ensure only authorized personnel can communicate with the target application environment.

Exploitation status

Public Exploit Available: No (exploit_available: false)

Analyst recommendation

The reliance on weak entropy for authentication secrets creates a significant security gap. Organizations should prioritize updating their Spring Tools environment as soon as the vendor provides a fix to eliminate the risk of unauthorized remote-restart commands.
