Path Traversal in Vibe-Trading Persistent Memory Store

Executive Summary

Vibe-Trading versions before 0.1.10 contain a path traversal vulnerability in the remember tool. This flaw arises because the application improperly handles the memory_type parameter, allowing attackers to supply malicious path traversal sequences.

By exploiting this, attackers can cause the application to write arbitrary Markdown files outside the intended memory root directory on the filesystem, potentially placing files in unintended locations.

Impact Analysis

The vulnerability allows attackers with some level of access (low privileges) to write arbitrary Markdown files outside the designated memory directory.

This can lead to unauthorized file creation on the filesystem, which might be used to manipulate application behavior, store malicious content, or disrupt normal operations.

However, the impact is limited to file creation and does not affect frontend behavior, live trading, or API settings.

Detection Guidance

This vulnerability involves the manipulation of the memory_type parameter in the persistent memory store to write arbitrary Markdown files outside the intended directory. Detection can focus on monitoring file writes to unexpected locations or inspecting usage of the remember tool with suspicious memory_type values containing path traversal sequences such as '../'.

Suggested commands to detect potential exploitation attempts include searching for Markdown files created outside the expected memory root directory and monitoring application logs for errors related to invalid memory_type parameters.

• Find Markdown files outside the intended directory (example path /var/vibe-trading/memory):
• find /var/vibe-trading -type f -name '*.md' ! -path '/var/vibe-trading/memory/*'
• Search application logs for suspicious memory_type values containing path traversal sequences:
• grep -r '\.\./' /var/log/vibe-trading/

Mitigation Strategies

To mitigate this vulnerability, immediately upgrade Vibe-Trading to version 0.1.10 or later, where the issue has been fixed by validating the memory_type parameter against an allowlist of valid categories.

If upgrading is not immediately possible, implement input validation to reject memory_type values containing path traversal sequences or unexpected values before they reach the persistent memory store.

Additionally, monitor and restrict file system permissions to prevent unauthorized file writes outside the intended directories.
