Description
SIP signaling stack in Verizon IMS (unspecified version) implements SIP signaling without IPsec integrity protection (missing Security-Client/Security-Server headers and ESP traffic), which allows an on-path attacker to compromise confidentiality, integrity, and authenticity of VoLTE signaling via passive monitoring and active manipulation of unsecured SIP messages over the radio and core network.
