Technical Details

what runs on :6619

Odette File Transfer Protocol (OFTP) is a protocol designed for the exchange of electronic documents between business partners, widely adopted in the European automotive industry. It supports both point-to-point and store-and-forward messaging, facilitating automated, reliable, and efficient file transfers of EDI messages, CAD drawings, and other sensitive business data.

With the advent of OFTP v2, the protocol incorporated significant security enhancements, including support for encryption, digital signatures, and file compression. To further secure communications, OFTP can run over TLS/SSL, providing encrypted channels to protect data integrity and confidentiality during transit. Communication occurs over TCP or UDP on port 6619, using SSL/TLS sessions to encapsulate the OFTP dialogue.

OFTP over TLS ensures interoperability across diverse platforms, with support for large file sizes, exchange of signed/encrypted files, and features such as session-level security, restartable transfers in case of interruptions, and detailed session logging. This makes it well-suited for high-assurance file exchanges required by supply chains and industrial partners.

security overview

Common vulnerabilities:

  • Misconfigured TLS/SSL parameters, such as outdated cipher suites or expired certificates, reducing encryption effectiveness
  • Excessive exposure via open ports, increasing the attack surface for unauthorized access attempts
  • Potential software vulnerabilities within OFTP implementations or middleware
  • Downgrade attacks targeting the encryption to weaken security
  • Lack of mutual authentication, making man-in-the-middle attacks possible

Common mitigations:

  • Enforce strong, up-to-date SSL/TLS configurations, using modern cipher suites and protocols (TLS 1.2 or higher)
  • Use mutual authentication with validated certificates to ensure both parties' identities
  • Regularly update and patch OFTP software to remediate known vulnerabilities
  • Apply access control lists (ACLs) and firewall rules to restrict exposure and reduce attack surface
  • Employ robust monitoring and logging to detect unauthorized access attempts
  • Use intrusion detection/prevention systems (IDS/IPS) to identify suspicious activity
