Security readout for executives and security teams
D-Link DPH-540 and DPH-541 SIP phones may accept call setup messages from systems other than the intended call server. An attacker could contact the phone directly and present forged caller ID, creating impersonation and social-engineering risk for any remaining deployed devices. Exposure is likely limited to organizations still using D-Link DPH-540 or DPH-541 phones, especially where SIP signaling can reach handsets from untrusted networks. Treat this as a legacy VoIP exposure issue. It is not shown as actively exploited in the provided sources, but it can enable caller impersonation against affected phones. Prioritize if these devices remain deployed or reachable beyond the trusted call-control network. Mitigation focus: Check D-Link or archived vendor guidance for firmware or configuration fixes.; Restrict SIP traffic to approved call server IP addresses at network controls.; Segment legacy VoIP phones from untrusted networks and user workstations..
