Summary

Finding: DoS Attack via Range Requests (CVE-2018-15756, https://spring.io/security/cve-2018-15756)
Repo: COG-GTM/ftgo-monolith

Spring Boot 2.0.3.RELEASE manages Spring Framework 5.0.7, whose ResourceHttpRequestHandler is vulnerable to DoS via many/overlapping Range headers; ftgo-application serves static resources (static/index.html, js/app.js, css/style.css) so the handler is active.

Fix approach: bump springBootVersion in gradle.properties from 2.0.3.RELEASE to 2.0.9.RELEASE (the final 2.0.x patch), which manages Spring Framework 5.0.13 (>= 5.0.10 where the issue was fixed) while staying on the same Spring Boot minor line and Gradle 4.10 wrapper.

Note: local Gradle build could not be verified in this session because Maven Central returned HTTP 429 (rate limited) for all artifact downloads; relying on CI.
