Uncontrolled Resource Consumption


Severity High
Score 7.5/10


In Spring Framework versions 6.0.0-M6 through 6.0.13, and 6.1.0-M1 through 6.1.0-RC2, a user can provide specially crafted HTTP requests that may cause a Denial-of-Service (DoS) condition. Specifically, an application is vulnerable when all of the following are true: 1.The application uses "Spring MVC" or "Spring WebFlux". 2."io.micrometer:micrometer-core" is on the classpath. 3.An "ObservationRegistry" is configured in the application to record observations. Typically, Spring Boot applications need the "org.springframework.boot:spring-boot-actuator" dependency to meet all conditions.

CWE-400 - Uncontrolled resource consumption

An uncontrolled resource allocation attack (also known as resource exhaustion attack) triggers unauthorized overconsumption of the limited resources in an application, such as memory, file system storage, database connection pool entries, and CPU. This may lead to denial of service for valid users and degradation of the application's functionality as well as that of the host operating system.
