CVE-2020-5410: VMware Tanzu Spring Cloud Config Directory Traversal Vulnerability

High severity, CVSS 7.5. Actively exploited: in CISA KEV since 2022-03-25. EPSS: 95.6% chance of exploitation in the next 30 days.

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.
