## Overview

An access-control vulnerability has been identified in the web server configuration. Some resources intended for on-device use only could be accessed remotely by an unauthenticated attacker with network access to the web interface.
The accessible resources do not expose credentials or provide administrative functionality, but may include non-public device content, such as screen-saver content or assets used by the web interface.

## Affected

- `cynap_pro_cynap_core_pro_cynap_receiver_cynap_pure_cynap_pure_mini_cynap_pure_pro < 1.78a`
- `cynap_pure_next_gen_cynap_bridge < 2.00d`
- `cynap_videobar < 1.72e`
- `cynap_cynap_core_cynap_pure_sdm all versions`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.

### Workarounds

Until an update can be applied, consider the following measures where operationally feasible:
  *  Restrict network access to the web management interfaces on TCP ports 80 and 443 to trusted hosts only.


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.
