Executive Summary

This vulnerability is a path traversal issue in FlowCI flow-core-x up to version 1.23.49. It exists in the FileHelper.unzip function of the file common/src/main/java/com/flowci/common/helper/FileHelper.java. The flaw allows an attacker to manipulate file paths, potentially accessing files outside intended directories. The attack can be performed remotely but requires high complexity and is considered difficult to exploit.

Impact Analysis

If exploited, this vulnerability could allow an attacker to read sensitive files on the server, including configuration files, source code, or other confidential data. This may lead to unauthorized access, data leaks, or further attacks on the system. The impact depends on the server's file permissions and the data stored.

Compliance Impact

This vulnerability could lead to unauthorized data access, violating GDPR's data protection principles or HIPAA's security requirements. Organizations using affected FlowCI versions may face compliance violations, legal penalties, or reputational damage if sensitive data is exposed.

Mitigation Strategies

Immediately upgrade FlowCI flow-core-x to a version beyond 1.23.49 where the vulnerability is patched. If no patch is available, disable the FileHelper.unzip function or restrict network access to the vulnerable component.
