Attack-Flow Graph

Executive Summary

This vulnerability exists in RAGapp versions up to 0.1.5, specifically in the functions FileHandler.upload_file and FileHandler.remove_file within the Knowledge File Handler component. It allows an attacker to perform a path traversal attack by manipulating file paths. This means an attacker can potentially access or modify files outside the intended directories. The attack can be executed remotely, and a fix is pending acceptance.

Impact Analysis

The vulnerability can allow an attacker to access or modify files on the affected system that they should not have permission to. This could lead to unauthorized disclosure of sensitive information, data tampering, or disruption of service. Since the attack can be performed remotely, it increases the risk of exploitation without physical access to the system.
