CVE-2020-5410: Directory Traversal with spring-cloud-config-server

Noroxi assessment

Priority: Now (action score 89/100)

  • CISA has confirmed exploitation in the wild (Mar 25, 2022). Remediation deadline for US federal agencies: Apr 15, 2022.
  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 95.5% (FIRST EPSS); higher than 99.8% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: org.springframework.cloud:spring-cloud-config-server (Maven) 2.1.9, 2.2.3.

Patch today or shut off access. Upgrade to org.springframework.cloud:spring-cloud-config-server (Maven) 2.1.9, 2.2.3 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

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.
