Unauthenticated UDP Packet Injection in Spring Integration

Publication date: 2026-08-27

Last updated on: 2026-09-02

Assigner: VMware

Description

An unauthenticated remote attacker who can send a single UDP packet to a Spring Integration UDP inbound adapter can cause the server to emit an outbound UDP datagram to an arbitrary internal or external host and port of the attacker's choosing. Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0 - 6.5.10 Spring Integration 6.4.0 - 6.4.12 Spring Integration 5.5.21 and earlier

CWE-918	The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.

Attack-Flow Graph

Executive Summary

This is a Server-Side Request Forgery (SSRF) vulnerability in Spring Integration UDP adapters. An unauthenticated remote attacker sends a single UDP packet to a vulnerable inbound adapter, which then sends an outbound UDP datagram to any host and port the attacker chooses. The payload is a 36-byte UUID string.

Detection Guidance

To detect this vulnerability, monitor for unexpected outbound UDP traffic from systems running vulnerable Spring Integration versions. Check for UDP packets sent to unusual ports or external hosts. Use network monitoring tools like tcpdump or Wireshark to capture UDP traffic from Spring Integration processes. Example command: tcpdump -i any -n udp port 10000 -w spring_udp_traffic.pcap.

Impact Analysis

An attacker could use this to scan internal networks, trigger UDP services like memcached or SNMP on internal hosts, or use the server as a reflection point for amplification attacks. This could lead to information disclosure or denial of service.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA by enabling unauthorized network reconnaissance or data exfiltration through UDP SSRF. Attackers could scan internal networks, interact with sensitive services, or use the server as a relay, which may violate data protection requirements for confidentiality and integrity.

Mitigation Strategies

Immediately upgrade to fixed versions of Spring Integration: 7.1.1 (OSS), 7.0.6 (OSS), 6.5.11, 6.4.13, or 5.5.22 (Enterprise Support Only). No additional mitigation steps are required beyond upgrading. Ensure all affected systems are updated promptly to prevent exploitation.
