Technical Details

what runs on :5445

Cisco Unified Video Advantage (CUVA) is a Cisco proprietary system that adds video capabilities to Cisco IP Phones, providing end users with integrated voice and video communications. By leveraging existing Cisco Voice-over-IP infrastructure, CUVA manages signaling and media streams to enable smooth video call experiences. It is compatible with a wide range of Cisco IP Phones and is often integrated within Cisco Unified Communications Manager for centralized management.

Port 5445 (UDP) is predominantly used by CUVA for establishing and managing video streams. It facilitates the rapid, real-time transmission of video packets between endpoints, reducing the impact of network latency and jitter. The system usually relies on RTP (Real Time Protocol) over UDP for transmitting media. As video conferencing is interactive and delay-sensitive, UDP is preferred over TCP to minimize delays caused by retransmissions.

In deployment scenarios, this port must be allowed through internal network firewalls and quality of service (QoS) parameters should be carefully tuned for optimal video quality. Interoperability with various Cisco collaboration solutions ensures a seamless user experience, leveraging this dedicated port for media streaming.

security overview

Common vulnerabilities associated with UDP port 5445 for Cisco Unified Video Advantage may include:

  • Exposure to denial-of-service (DoS) attacks that flood endpoints with excessive UDP packets
  • Possibility of unauthorized access or eavesdropping if media streams are intercepted
  • Exploitation of unencrypted traffic by attackers for replay or man-in-the-middle attacks

Mitigations include:

  • Enforcing strong network segmentation and access-control lists (ACLs) to limit exposure
  • Using secure VPNs or encrypted media channels where possible to protect data integrity and confidentiality
  • Applying rate-limiting and intrusion prevention systems to detect and block abnormal traffic patterns
  • Keeping Cisco software and firmware up to date to patch known vulnerabilities
  • Regular auditing and monitoring of network traffic involving video conferencing endpoints
