Port 3299SAP Router

SAP Router is an application-level proxy used within SAP environments to securely route traffic and connections between SAP clients and servers. It acts as an intermediary that regulates network communication, enabling organizations to protect internal SAP systems by controlling external access without exposing sensitive systems directly to untrusted networks..

Technical Details

what runs on :3299

SAP Router is a specialized proxy software developed by SAP, which facilitates secure communication between SAP clients and servers across network boundaries. It is typically deployed at the edge of the corporate network to manage and channel incoming and outgoing SAP traffic, acting as a firewall-like routing agent for SAP protocols.

Operating on TCP port 3299, SAP Router inspects, filters, and forwards SAP-specific requests based on predefined routing rules. It supports multiple hop routing, where requests can pass through multiple SAP Routers before reaching the destination SAP application server, thereby enabling complex network topologies and secure segmentations of SAP systems.

Moreover, SAP Router can be configured with access control lists and digital certificates to authorize connections and encrypt data flows. This makes it an essential component for SAP landscapes, especially when supporting remote site connectivity, SAP support access, and interactions across potentially insecure networks.

security overview

Common vulnerabilities associated with SAP Router include:

  • Unauthorized access due to misconfigured access control lists (ACLs), which can allow attackers to pivot into backend SAP systems.
  • Lack of encryption on certain connections, potentially exposing sensitive data in transit.
  • Use of default or weak routing passwords, making brute-force attacks viable.

Mitigations typically involve:

  • Regularly reviewing and hardening the SAP Router ACL files to explicitly define allowed hosts.
  • Enforcing strong routing passwords and rotating them periodically.
  • Enabling route encryption using SAP-provided certificates to secure data in transit.
  • Keeping SAP Router software updated to patch known vulnerabilities.
  • Limiting network exposure of port 3299 to only trusted hosts and networks, using internal firewalls.
  • Monitoring SAP Router logs for suspicious activities and unsuccessful routing attempts.
