Attack-Flow Graph

Executive Summary

This vulnerability is a potential arbitrary file read and Server-Side Request Forgery (SSRF) issue in Spring Cloud Function affecting versions 5.0.0 to 5.0.3, 4.3.0 to 4.3.4, and 4.2.0 to 4.2.7. It allows attackers to read arbitrary files or make unauthorized requests from the server.

Detection Guidance

Detection involves checking for vulnerable Spring Cloud Function versions. Use commands like 'curl -s http://<target>/actuator/env' or 'curl -s http://<target>/actuator/health' to inspect endpoints. Verify version via 'curl -s http://<target>/actuator/info' or check dependency files (pom.xml, build.gradle).

Impact Analysis

An attacker could exploit this to read sensitive files on the server or perform SSRF attacks, potentially accessing internal systems or data. This could lead to data breaches or unauthorized access to resources.

Compliance Impact

This vulnerability could lead to unauthorized data access, violating GDPR's data protection requirements or HIPAA's safeguards for protected health information. Compliance may be compromised if sensitive data is exposed.

Mitigation Strategies

Upgrade to fixed versions: Spring Cloud Function 5.0.4, 4.3.5 (Enterprise), or 4.2.8 (Enterprise). No additional mitigation steps are required.
