Spring Boot vulnerability analysis and mitigation
Overview
In Spring Boot versions 2.7.0 - 2.7.17, 3.0.0-3.0.12, and 3.1.0-3.1.5, a vulnerability was discovered that allows users to cause a denial-of-service (DoS) condition through specially crafted HTTP requests. The vulnerability affects applications that use Spring MVC or Spring WebFlux and have org.springframework.boot:spring-boot-actuator on the classpath. This vulnerability was disclosed on November 27, 2023, and was assigned CVE-2023-34055 (Spring Advisory).
Technical details
The vulnerability has been assigned a CVSS v3.1 base score of 6.5 (MEDIUM) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H. The vulnerability specifically targets the web observations functionality in Spring Boot's actuator component. The attack vector is network-accessible (AV:N) with low attack complexity (AC:L), requiring low privileges (PR:L) and no user interaction (UI:N) (NVD).
Impact
When successfully exploited, this vulnerability can lead to a denial-of-service (DoS) condition, affecting the availability of the application. The impact is specifically focused on availability (A:H) with no impact on confidentiality (C:N) or integrity (I:N) (NVD).
Mitigation and workarounds
Users of affected versions should upgrade to the following patched versions: Spring Boot 2.7.x users should upgrade to 2.7.18, Spring Boot 3.0.x users should upgrade to 3.0.13, and Spring Boot 3.1.x users should upgrade to 3.1.6.
