Attack-Flow Graph

Executive Summary

modelscope Agentscope versions 1.0.0 to 1.0.8 has a Path Traversal vulnerability in the insert_text_file function. This allows an attacker with local access to read arbitrary files on the system by manipulating file paths.

Detection Guidance

To detect this vulnerability, check if AgentScope versions 1.0.18 through 1.0.19.post1 are installed. Inspect the file src/agentscope/tool/_text_file/_write_text_file.py for the insert_text_file function at line 12. Monitor for unauthorized file writes outside intended directories.

Impact Analysis

An attacker could exploit this to access sensitive files, including configuration files, user data, or system files. This may lead to data breaches, privilege escalation, or further system compromise depending on the exposed files.

Compliance Impact

This vulnerability could lead to unauthorized access to personal or sensitive data, violating GDPR and HIPAA requirements for data protection and confidentiality. Organizations may face legal penalties, fines, or reputational damage if exploited.

Mitigation Strategies

Immediately update Agentscope to a version beyond v1.0.8. If updating is not possible, disable file insertion features or restrict access to vulnerable endpoints. Monitor for unusual file access patterns.
