CVE Alert: CVE-2016-7836 – Sky Co., LTD. – SKYSEA Client View

Risk verdict

High risk: active exploitation data increases likelihood of remote code execution on vulnerable SKYSEA Client View deployments.

Why this matters

Successful exploitation yields total compromise of the affected host and potential footholds for further access within trusted networks. Enterprise environments relying on this product for endpoint management may face rapid deployment of attacker code, data exposure, or disruption of security workflows if the console is reachable from attackers.

Most likely attack path

• Attack vector: network, with no user interaction required and no privileges needed.
• Precondition: direct or routable access to the management console over TCP; flawed authentication handling could be exploited remotely.
• Impact path: remote code execution leading to full system compromise; unchanged scope indicates access effects stay within the compromised asset rather than propagating to different security domains.

Who is most exposed

Organizations with on-prem SKYSEA Client View installations or exposed management consoles (especially accessible from less-trusted network segments or the internet) are at highest risk; deployments where the console is widely reachable and not properly segmented are particularly vulnerable.

Detection ideas

• alert on unusual authentication attempts or malformed TCP sessions targeting the management console port.
• detect anomalous process creation or memory spikes for the SKYSEA Client View service after connection attempts.
• monitor for unexpected code execution or shell-like commands initiated by the SkySea binary.
• scan logs for repeated failed logins followed by rapid success from unknown subnets.
• correlates between console access events and spikes in privileged actions.

Mitigation and prioritisation

• Patch to latest vendor version or apply all available fixes; verify compatibility in test environment before broad rollout.
• Restrict network access to the management console (IP allowlists, VPN-only access, MFA for admin sessions).
• Implement network segmentation and firewall rules to limit inbound traffic to trusted admin networks.
• Disable internet exposure of the console where feasible; deploy hop hosts or jump servers.
• Change-management: plan staged upgrade, with rollback and validation checks; notify SOC and perform post-deploy monitoring.
