CyberData 011209 SIP Emergency Intercom is included in the CISA ICS advisory batch; while lower-profile than large OT platforms, SIP-based emergency intercoms with hardened credential or RCE vulnerabilities present a physical security and communications integrity risk in facilities that depend on them for emergency notification. Review CISA advisory details for affected firmware versions and apply vendor patches; if patching is not immediately available, isolate affected devices from untrusted network segments.
