Attack-Flow Graph

Executive Summary

This vulnerability involves Spring Cloud Function Azure potentially logging sensitive data. It affects versions 5.0.0-5.0.3, 4.3.0-4.3.4, and 4.2.0-4.2.7. The issue arises when sensitive information is inadvertently included in logs during function execution.

Detection Guidance

To detect this vulnerability, check if your system is running affected versions of Spring Cloud Function (5.0.0-5.0.3, 4.3.0-4.3.4, or 4.2.0-4.2.7). Use commands like 'find / -name spring-cloud-function-*.jar' to locate the library. Verify version details in the JAR manifest or logs.

Impact Analysis

If exploited, this vulnerability could expose sensitive data in logs, leading to unauthorized access or compliance violations. The impact is limited due to high attack complexity and requires user interaction, but sensitive data exposure remains a risk.

Compliance Impact

Logging sensitive data may violate GDPR and HIPAA requirements for data protection and confidentiality. Organizations using affected versions could face compliance penalties if sensitive data is exposed through logs.

Mitigation Strategies

Upgrade to fixed versions: Spring Cloud Function 5.0.4 for OSS, or 4.3.5 and 4.2.8 for Enterprise Support. No additional mitigation steps are required.
