Remediation/Mitigation Strategy: CVE-2025-27106 - Remote Code Execution in binance-trading-bot

This document outlines the vulnerability, severity, known exploit, and recommended remediation and mitigation steps for CVE-2025-27106, a Remote Code Execution vulnerability in the binance-trading-bot application.

1. Vulnerability Description:

  • Vulnerability: Command Injection
  • Affected Software: binance-trading-bot (versions prior to 0.0.100)
  • Location: /restore endpoint
  • Description: The binance-trading-bot application is vulnerable to command injection in the /restore endpoint. When a user uploads a file through this endpoint, the filename is passed to shell.exec without proper sanitization beyond basic path normalization. This allows an attacker to inject arbitrary shell commands through a specially crafted filename.

2. Severity:

  • CVSS Score: 8.8 (High)
  • CVSS Vector: (Based on provided data, we can infer parts of the vector, but a full vector would be needed for accurate representation.) Likely including components such as: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H (Network, Low Complexity, Low Privileges, No User Interaction, Unchanged Scope, High Confidentiality Impact, High Integrity Impact, High Availability Impact)
  • Impact: Remote Code Execution (RCE). Successful exploitation allows an attacker to execute arbitrary code on the host system with the privileges of the user running the binance-trading-bot application. This could lead to complete system compromise, data theft, and denial of service.

3. Known Exploit:

  • Exploit Details: An authenticated user can upload a file with a malicious filename containing shell commands to the /restore endpoint. The application then executes the file’s name as part of a shell command. For example, uploading a file named ; rm -rf / ; (extremely dangerous, DO NOT TRY THIS ON A PRODUCTION SYSTEM) would attempt to delete all files on the system. A more targeted exploit might install a backdoor or exfiltrate sensitive data.

4. Remediation:

  • Primary Recommendation: Upgrade to version 0.0.100 or later. This version includes a fix that addresses the command injection vulnerability. This is the most effective and recommended approach.

    • Procedure: Follow the official upgrade instructions provided by the binance-trading-bot developers. This usually involves downloading the latest version, stopping the existing bot, replacing the old files with the new ones, and restarting the bot.

5. Mitigation (If Upgrade is not Immediately Possible):

  • Important Note: Mitigation steps are not a replacement for patching. They only provide a temporary reduction in risk until a proper upgrade can be performed. These mitigations may break functionality and should be thoroughly tested in a non-production environment before deployment.

    • Input Validation: Implement strict input validation on the filename received by the /restore endpoint. Sanitize the filename by:

      • Whitelisting allowed characters (e.g., alphanumeric characters, underscores, hyphens, and periods).
      • Blacklisting or escaping potentially dangerous characters like semicolons, backticks, pipes, ampersands, and dollar signs. Carefully consider the impact of blocking characters that might legitimately be used in filenames.
      • Limiting the maximum filename length.
      • Normalizing the path using functions specifically designed to avoid path traversal issues.

    • Least Privilege: Run the binance-trading-bot application with the lowest possible privileges necessary for its operation. This will limit the impact of a successful exploit. Create a dedicated user account specifically for running the bot and grant it only the required permissions.

    • Disable the /restore Endpoint (If feasible): If the /restore endpoint is not a critical feature, consider temporarily disabling it until a proper upgrade can be applied. This will eliminate the attack vector. Modify the application’s configuration or code to remove or block access to the endpoint.

    • Web Application Firewall (WAF) Rules (If applicable): Implement WAF rules to detect and block malicious requests to the /restore endpoint. The WAF rules should be configured to look for patterns indicative of command injection attempts in the filename parameter.

    • Monitoring and Alerting: Implement monitoring to detect suspicious activity related to the /restore endpoint, such as failed login attempts, unexpected file uploads, or unusual process execution. Configure alerts to notify administrators of any suspicious activity.

6. Testing:

  • After applying either the remediation or mitigation steps, thoroughly test the binance-trading-bot application to ensure that the vulnerability has been addressed and that the mitigation steps do not introduce any unintended side effects. Include penetration testing and vulnerability scanning.

7. Communication:

  • Communicate the vulnerability and the remediation/mitigation steps to all affected users of the binance-trading-bot application. Clearly explain the risks associated with the vulnerability and the importance of applying the recommended steps.

8. Disclaimer:

This remediation/mitigation strategy is provided as a guideline and may need to be adapted to your specific environment. It is essential to consult with security professionals and thoroughly test all changes before deploying them to a production environment.
