Attack-Flow Graph

Executive Summary

This vulnerability involves a security issue in Spring Cloud Stream where a partition interceptor may be improperly added while sending messages. This could lead to unintended message handling or interception in versions 5.0.0 to 5.0.2, 4.3.0 to 4.3.3, and 4.2.0 to 4.2.6.

Detection Guidance

Detection involves checking the installed versions of Spring Cloud Stream. Use commands like 'find / -name spring-cloud-stream-*.jar' to locate the library and 'cat /path/to/version.properties' or 'java -jar /path/to/app.jar version' to check the version. Compare against affected ranges: 5.0.0-5.0.2, 4.3.0-4.3.3, 4.2.0-4.2.6.

Impact Analysis

The improper addition of a partition interceptor could allow unauthorized message interception or manipulation, potentially leading to data leaks or integrity issues. The impact is limited due to a low CVSS score of 3.1, indicating a lower severity.

Compliance Impact

The vulnerability does not directly impact compliance with GDPR or HIPAA as it involves improper message interceptor handling rather than data exposure or privacy violations. However, if exploited, it could potentially lead to unauthorized message processing, which may indirectly affect data integrity or confidentiality requirements under these regulations.

Mitigation Strategies

Upgrade to fixed versions: Spring Cloud Stream 5.0.3, 4.3.4 (Enterprise only), or 4.2.7 (Enterprise only). No additional mitigation steps are required beyond upgrading.
