Description
Foscam VD1 Video Doorbell before V5.3.13_1072 is vulnerable to Cleartext Transmission of Sensitive Information. The device transmits sensitive Session Description Protocol (SDP), including ICE credentials and candidates, in cleartext over network interfaces. An attacker with network visibility can intercept these credentials to hijack media streams or authenticate to Foscam's TURN/relay infrastructure to forward arbitrary traffic at the vendor's expense.
