Spring Cloud Config vulnerabilities

A directory traversal vulnerability in Spring Cloud Config allows attackers to access arbitrary files via a crafted URL. The issue affects the spring-cloud-config-server module serving text and binary files.

The Spring Cloud Config Monitor is susceptible to Denial of Service attacks via malicious payloads. Affects Spring Cloud Config versions 5.0.0-5.0.4, 4.3.0-4.3.4, 4.0.0-4.2.8, and 3.1.14 and earlier.

Spring Cloud Config Server native environment repository allows exposure of configuration files outside of the configured repository path. Affected versions: Spring Cloud Config 5.0.0-5.0.4, 4.3.0-4.3.4, 4.0.0-4.2.8, and 3.1.14 and earlier.

Missing Authentication for Critical Function vulnerability in Spring Cloud Config allows unvalidated Webhook requests to the /monitor endpoint. Affects versions from 5.0.0 through 5.0.4, from 4.3.0 through 4.3.4, from 4.0.0 through 4.2.8, and through 3.1.14.

The base directory (spring.cloud.config.server.svn.basedir) used by the Spring Cloud Config Server to clone SVN repositories to is susceptible to time-of-check-time-of-use (TOCTOU) attacks. Affected versions: Spring Cloud Config 5.0.0-5.0.4, 4.3.0-4.3.4, 4.0.0-4.2.8, 3.1.14 and earlier.

A vulnerability in Spring Cloud Config allows a client to craft a request to the config server, potentially exposing secrets from unintended GCP projects when Google Secrets Manager is used as a backend.
