Security readout for executives and security teams

This issue can expose internal high-availability and device identity details from certain Peplink Balance appliances. The disclosed data is not full device control, but it can help an attacker map network infrastructure and prepare more targeted attacks if the device interface is reachable. Exposure is limited to listed Peplink Balance models running firmware before 7.0.1 build2093, especially where the management or HA-related web interface is reachable by untrusted users. Treat this as a network-edge information exposure. Prioritize devices reachable from the internet or partner networks, then complete firmware remediation and access restriction during the next operational window. Mitigation focus: Upgrade affected Peplink Balance devices to 7.0.1 build2093 or later vendor-recommended firmware.; Restrict management and HA web interfaces to trusted administrative networks only.; Remove any internet exposure of administrative CGI endpoints where possible..
