Description

Spring Cloud Config, versions 2.2.x prior to 2.2.3, versions 2.1.x prior to 2.1.9, and older unsupported versions allow applications to serve arbitrary configuration files through the spring-cloud-config-server module. A malicious user, or attacker, can send a request using a specially crafted URL that can lead to a directory traversal attack.

Detail

Spring Cloud Config is an open-source tool used to centralize and manage the configuration of microservices-based applications. By using Spring Cloud Config, developers can externalize application configuration into a centralized location, making it easier to manage changes across multiple environments. This tool provides a configuration server, client libraries, and other components for managing and distributing configuration data.

CVE-2020-5410 is a vulnerability that has been detected in Spring Cloud Config. This vulnerability affects versions 2.2.x prior to 2.2.3, versions 2.1.x prior to 2.1.9, and older unsupported versions. It allows malicious users or attackers to send specially crafted URLs that can lead to directory traversal attacks. Through this attack, the attackers can access arbitrary configuration files served through the spring-cloud-config-server module.

This vulnerability can lead to serious consequences when exploited. Attackers can gain access to sensitive configuration files, allowing them to perform unauthorized actions, such as modifying user data, stealing credentials and other sensitive data, and even taking control of the entire system. These attacks can have numerous consequences that can impact the organization's reputation, as well as the finances, privacy, and trust of the affected individuals.
