IMS Security Analysis
Comprehensive analysis of IP Multimedia Subsystem (IMS) security, including VoLTE, VoWiFi, and RCS security vulnerabilities and attack vectors.
IMS Architecture Overview
The IP Multimedia Subsystem (IMS) is a framework for delivering IP multimedia services. It provides a standardized architecture for operators to offer voice, video, messaging, and other multimedia services over IP networks.
IMS Components & Vulnerabilities
Call Session Control Function (CSCF)
Core signaling control for IMS sessions
Key Vulnerabilities:
SIP Message Manipulation
Authentication Bypass
DoS Attacks
Home Subscriber Server (HSS)
Central database for subscriber information
Key Vulnerabilities:
Data Exposure
Unauthorized Access
Profile Manipulation
Media Gateway Control Function (MGCF)
Interworking with circuit-switched networks
Key Vulnerabilities:
Protocol Translation Attacks
Media Manipulation
Signaling Interception
Application Server (AS)
Hosts and executes IMS services
Key Vulnerabilities:
Service Logic Exploitation
Privilege Escalation
Data Leakage
IMS Attack Vectors
VoLTE Call Interception
High
Intercepting voice calls over LTE networks through IMS vulnerabilities
Potential Impact:
