CVE-2021-4469: Denver SHO-110 IP Camera Unauthenticated Snapshot Access

Denver SHO-110 IP cameras expose a secondary HTTP service on TCP port 8001 that provides access to a '/snapshot' endpoint without authentication. While the primary web interface on port 80 enforces authentication, the backdoor service allows any remote attacker to retrieve image snapshots by directly requesting the 'snapshot' endpoint. An attacker can repeatedly collect snapshots and reconstruct the camera stream, compromising the confidentiality of the monitored environment.

Security readout for executives and security teams

Denver's SHO-110 home security camera quietly runs a second web service that hands out live snapshots to anyone on the network without asking for a password. Even though the main camera login screen is protected, this hidden door lets attackers watch what the camera sees, turning a privacy device into a surveillance leak. Limited to environments running Denver SHO-110 cameras directly reachable on TCP/8001, typically small office, retail, or residential deployments where the device is internet-exposed or sits on a flat LAN reachable by untrusted users or guest Wi-Fi. High priority for any site still running SHO-110 cameras: treat as a privacy and physical-security incident risk, segment or replace the devices now, and confirm the secondary port is unreachable from untrusted networks. Mitigation focus: Block inbound and lateral access to TCP/8001 on every SHO-110 at the firewall and switch.; Move SHO-110 cameras onto an isolated VLAN with no internet ingress or guest reachability.; Check Denver vendor pages for current firmware or security guidance before retaining the device..
