CVE-2024-54362

Remediation / Mitigation Strategy: CVE-2024-54362 - GetShop ecommerce Path Traversal

Vulnerability Description:

  • Type: Path Traversal
  • Affected Software: GetShop ecommerce
  • Affected Versions: All versions up to and including 1.3

Severity:

  • CVSS Score: 8.1 (High)

Known Exploit:

  • The vulnerability allows attackers to access files and directories outside the intended webroot by manipulating file paths in requests. This could potentially lead to:
    • Reading sensitive files (configuration files, database credentials, etc.)
    • Executing arbitrary code on the server (depending on server configuration and file permissions)
    • Information Disclosure
    • Unauthorized Access

Remediation Strategy:

  1. Upgrade GetShop ecommerce: Immediately upgrade GetShop ecommerce to a patched version that addresses this vulnerability. Contact the vendor for details on patched versions or available updates.
  2. Input Validation: Implement strict input validation on all user-supplied input that is used in file path construction. Specifically, sanitize file paths to prevent traversal attempts:
    • Whitelist Allowed Characters: Only allow a restricted set of characters in file path inputs (alphanumeric, underscore, dash, period if absolutely necessary).
    • Path Canonicalization: Use the realpath() function (or equivalent in your programming language) to resolve symbolic links and remove relative path components (., ..).
    • Blacklist Dangerous Sequences: Reject any input containing sequences like ../ or ..\ that could be used for path traversal.
  3. Access Control: Ensure the web server user has the minimal necessary permissions to access the files required for the application to function. Avoid granting the web server user write access to sensitive directories.
  4. Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) with rules to detect and block path traversal attempts. Configure the WAF to inspect request parameters and headers for malicious patterns.
  5. Regular Security Audits: Conduct regular security audits and penetration tests to identify and remediate potential vulnerabilities in the GetShop ecommerce installation and related infrastructure.
  6. File System Permissions: Configure the file system with restrictive permissions, following the principle of least privilege. Prevent the webserver user from having write access to sensitive files and directories.
  7. Content Security Policy: Implement Content Security Policy to reduce the risk of cross-site scripting attacks, this can help mitigate any payloads that are uploaded using the path traversal vulnerability.

Mitigation Strategy (If Immediate Patching is Not Possible):

If an immediate upgrade is not possible, implement the following mitigations:

  1. URL Rewriting: Use web server URL rewriting rules (e.g., .htaccess for Apache, nginx.conf for Nginx) to block access to sensitive files and directories based on URL patterns. For example, deny access to any URL containing ../.
  2. Isolate Critical Files: Move sensitive files outside of the webroot or into directories that are specifically protected by web server configuration.
  3. Monitor Logs: Enable detailed logging and monitor web server logs for suspicious activity, such as attempts to access unauthorized files. Set up alerts for potential path traversal attacks.
  4. Disable Directory Listing: Ensure directory listing is disabled on the web server to prevent attackers from discovering file paths.

Testing:

  • After implementing the remediation or mitigation steps, thoroughly test the application to ensure that the vulnerability has been successfully addressed and that the application still functions correctly. Conduct penetration testing to confirm the effectiveness of the implemented measures.

Note: Applying the latest security patches is the most effective way to address this vulnerability. The mitigation strategies are intended as temporary measures until a patch can be applied.
