Description
When the vSolution Matrix feature is enabled, affected devices may make current screen content available through an unauthenticated RTSP/RTP stream to hosts on the same network segment. The stream is not encrypted, which may allow an unauthenticated host to view or capture presentation content where network access is not otherwise restricted. This vulnerability only affects devices with the vSolution Matrix feature enabled.

Score: 7.1 High
EPSS: n/a
KEV: No
Impact: unauthenticated remote viewing of device screen content
Action: Apply Update
AI Analysis

Impact

The vulnerability allows an unauthenticated host on the same network segment to access the vSolution Matrix RTSP/RTP stream, which exposes current screen content in cleartext. The stream is not encrypted, so an attacker can capture or view presentation material without authorization. This flaw provides a confidentiality breach but does not grant code execution or denial of service capabilities.

Affected Systems

The flaw affects WolfVision Cynap Pro and Cynap Core Pro devices that have the vSolution Matrix feature enabled. No specific firmware versions are listed, so any device with this feature active is potentially vulnerable.

Risk and Exploitability

The CVSS score of 7.1 indicates moderate-to-high risk, and the EPSS score is not available, while the vulnerability is not listed in the CISA KEV catalog. The bypass requires only local network access; an attacker with network connectivity to the device’s VLAN can connect to RTSP ports (TCP 554/8554) and obtain cleartext streams. No credentials or additional privileges are required, making exploitation straightforward on poorly segmented networks.

Remediation

Vendor Workaround

Until an update can be applied, consider the following measures where operationally feasible: * Disable the "vSolution Matrix" feature if it is not required. * Restrict vSolution Matrix to networks that contain only trusted Matrix stations. If network separation is not feasible, block the following on a firewall: * Inbound RTSP control: TCP 554 and 8554. The device redirects TCP 554 to 8554, and Matrix clients connect to 8554. * Outbound audio and video multicast from the device: UDP 5500-5503 by default. * On Cynap Core and on Cynap Pro, also block inbound TCP 555 and 8555 and outbound UDP 5504-5507. These ports carry the second HDMI stream. * If the multicast port base is not 5500 (see device settings), replace 5500-5503 with that base through base+3, and 5504-5507 with base+4 through base+7. WolfVision recommends keeping devices up to date and using dedicated, managed network segments (VLAN or firewall zone) to restrict device access to trusted hosts only.


OpenCVE Recommended Actions

  • Install the vendor’s latest firmware update that addresses the vSolution Matrix RTSP issue.
  • If an update is not yet available, disable the vSolution Matrix feature in the device configuration to eliminate the unauthenticated stream.
  • Segregate the device onto a dedicated VLAN or firewall zone that limits access to trusted hosts only, and block or filter the RTSP and multicast ports (TCP 554/8554, TCP 555/8555, UDP 5500-5507) on the network perimeter if the feature remains enabled.
