Executive Summary

This vulnerability is an information disclosure flaw in GoClaw up to version 3.13.2. It involves the ExecTool.Execute function in goclaw/internal/http/tools_invoke.go, where the jq handler allows remote attackers to execute commands that can expose sensitive data like environment variables.

Detection Guidance

Check GoClaw logs for suspicious jq tool invocations via the POST /v1/tools/invoke endpoint. Monitor environment variable exposure in exec tool outputs. Verify if GOCLAW_GATEWAY_TOKEN or GOCLAW_ENCRYPTION_KEY appear in command outputs or logs.

Impact Analysis

An attacker with operator privileges could exploit this to retrieve the GOCLAW_GATEWAY_TOKEN or GOCLAW_ENCRYPTION_KEY. This token could then be used to gain unauthorized access to broader gateway capabilities via HTTP or WebSocket APIs, potentially leading to data breaches or system compromise.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles and HIPAA's security requirements for protected health information. Organizations using GoClaw may face compliance violations, legal penalties, and reputational damage due to potential data exposure.

Mitigation Strategies

Disable auto-approval for jq in exec tool policies. Add GOCLAW_GATEWAY_TOKEN and GOCLAW_ENCRYPTION_KEY to the credential scrub list. Update to the patched version if available. Restrict operator privileges and review exec tool configurations.
