This leads to disclosure of UE authentication and authorization information, and NF IP addresses and other topology information.\r\n\r\nThe adversary positioned on an IPX node may collect data over the N32 interface while a UE is roaming, if a SEPP has used encryption on some parts of the messages sent, or used a weak cipher for JWE encryption. Similarly, an adversary positioned on a SEPP can observe or easily decrypt signaling messages sent on the N32 interface.\r\n\r\nSimilarly, if the EPC interworking interface N26 for non-roaming is not encrypted, all subscriber signaling data may be exposed to adversary.\r\n\r\nAdversary may also use compromised virtualized network elements to (vSwitch/vRouter, Virtual Firewalls) to span traffic to a sniffing port for access to traffic flows and user/system data. In a virtualized environment access can be gained much more easily as the servers making up a function are more likely to be physically and virtually distributed and the SDN vSwitch would allow an adversary to fork IP packets flowing between hosts remotely much more easily. Such forking is very difficult to detect or prevent from within a 3GPP NF or VM, and adversaries may be able to read data in transit. \r\n\r\nAn adversary may utilize these observations for several follow-on techniques.\r\n\r\n", - "#### Addendum Name: Fronthaul\r\n##### Architecture Segments: User Plane, Control Plane, Roaming, Virtualization\r\n Adversaries may sniff network traffic to capture information about fronthaul user plane.\r\n\r\nORAN Alliance has defined the open fronthaul interface which connects one O-DU to one or more O-RUs inside the gNB. The fronthaul interface makes it possible to distribute the physical layer functionalities between RU and DU, and to control RU operations from DU. ORAN Alliance has selected a specific configuration (split 7.2x) for splitting of the physical layer among those proposed by 3GPP. The lower part of the physical layer (low PHY) resides in RU and performs Orthogonal Frequency Division Multiplexing (OFDM) phase compensation, inverse FFT and Cyclic Prefix (CP) insertion for frequency-to-time conversion in downlink, and FFT and CP removal in uplink. The physical layer in DU (high PHY) performs scrambling, modulation, layer mapping, and resource element mapping. Fronthaul consists of four types of interfaces: Control or C plane is used to carry control plane messages, User or U plane is used to carry user plane data, Synchronization or S plane is used to carry timing information and Management or M plane is used to carry management data.\r\n\r\nO-RAN fronthaul interface needs to implement strict performance requirements which includes very high throughput and very low latency. See clause 4.4 of [2]. Some security features may not be implemented by MNOs to meet those requirements and to reduce processing delay. Hence, Adversary on the Side (AoTS) attack on open fronthaul interface is possible which results in passive eavesdropping of U plane data. The adversary may use a simple sniffer device to monitor all U plane communications which is normally not encrypted at lower 3 layers (RLC, MAC and PHY). Confidentiality and integrity protection requirements are not specified by ORAN alliance for control, user and synchronization (CUS) planes, and those are mandatory for M plane. See clause 6.1 of [2] and clause 5.4 of [3].\r\n\r\nNote: The user plane data in PDCP and above layers remains encrypted on Fronthaul U plane and this eavesdrop attack will not impact any of those data unless PDCP security is also broken by the adversary.\r\n\r\n" - ], - "architecture-segment": "User Plane, Control Plane, Roaming, Virtualization", - "bluf": "Adversaries may sniff network traffic to capture information about an environment, including authentication material passed over the network.", - "criticalassets": [ - { - "Description": "Sensitive User signaling such as authentication data, user location for the N32 interface", - "Name": "UE data on roaming signaling interface" - }, - { - "Description": "User data for the N9 interface", - "Name": "UE data on roaming user plane interface" - }, - { - "Description": "Signaling data, provisioning data, service discovery", - "Name": "UP, CP Data" - }, - { - "Description": "Sensitive subscriber user plane data will be available to the adversary.", - "Name": "Sensitive subscriber data" - } - ], - "detections": [ - { - "detects": "Monitor processes which may sniff data.", - "fgdsid": "DS0009", - "name": "Process" - }, - { - "detects": "Monitor for allowed modifications relative to the agreed upon modifications per roaming agreements and agreements with IPX.", - "fgdsid": "DS0015", - "name": "Application Log" - }, - { - "detects": "Monitor commands given to NFs which may help data sniffing.", - "fgdsid": "DS0017", - "name": "Command" - }, - { - "detects": "Monitoring ability to detect new ports, devices on the network", - "fgdsid": "DS0039", - "name": "Asset" - }, - { - "detects": "Monitor if security configurations in O-RU and O-DU are downgraded to weak or no security levels.", - "fgdsid": "FGDS5022", - "name": "Monitor security configurations" - } - ], - "external_id": "FGT1040", - "kill_chain": [ - "fight:Discovery", - "fight:Collection", - "fight:Credential-Access" - ], - "mitigations": [ - { - "fgmid": "FGM5033", - "mitigates": "Use zero trust for NF protection", - "name": "Zero Trust" - }, - { - "fgmid": "M1020", - "mitigates": "Encrypt using TLS all links between NFs and between NF and SCP", - "name": "SSL/TLS Inspection" - }, - { - "fgmid": "M1040", - "mitigates": "Monitor to ensure configurations do not change from acceptable options", - "name": "Behavior Prevention on Endpoint" - }, - { - "fgmid": "M1041", - "mitigates": "Non-SBI: Use encryption (IPSec) on these interfaces.

A compromise of controls placed to maintain security zones or network segmentation based on IP networks, application groups or slices may allow an adversary to gain unauthorized access to networks or services. This may occur at a Core, RAN, Cloud or Slice boundary.\r\n\r\nOnce the adversary has infiltrated the internals of the network, it has ample opportunities and a much broader attack surface to explore. The adversary can, e.g., conduct privilege escalation and process injection for gaining administrative rights, attempt password cracking of valid user accounts on the nodes, exploit vulnerabilities in databases and file systems, and take advantage of improper configurations of routers and switches.\r\n\r\nThe boundaries of a network and its security zones can exist between various technologies, such as 4G and 5G, or between different partners, such as private networks, mobile operators, or Mobile Virtual Network Operators (MVNOs). These boundaries can also exist between different network components, such as radio access, core, edge, and cloud, as well as between national or international links and operator cores, and service providers or operator cores.\r\nIn some cases, firewalls may be used to separate these zones, such as SS7 protocol, Diameter protocol, 5G APIs, enhanced SCP (Service Communication Proxy), IP (Internet Protocol), SIP (Session Initiation Protocol), and GTP (GPRS Tunneling Protocols) firewalls. Alternatively, an interworking function may be used to translate one protocol into another.

The fronthaul interface makes it possible to distribute the physical layer functionalities between RU and DU, and to control RU operations from DU. ORAN Alliance has selected a specific configuration (split 7.2x) for splitting the physical layer among those proposed by 3GPP. The lower part of the physical layer (low PHY) resides in RU and performs Orthogonal Frequency Division Multiplexing (OFDM) phase compensation, inverse FFT and Cyclic Prefix (CP) insertion for frequency-to-time conversion in downlink, and FFT and CP removal in uplink. The physical layer in DU (high PHY) performs scrambling, modulation, layer mapping, and resource element mapping. Fronthaul consists of four types of interfaces: Control or C plane is used to carry control plane messages, User or U plane is used to carry user plane data, Synchronization or S plane is used to carry timing information and Management or M plane is used to carry management data.\r\n\r\nO-RAN fronthaul interface needs to implement strict performance requirements which includes very high throughput and very low latency. See clause 4.4 of [2]. Some security features may not be implemented by MNOs to meet those requirements and to reduce processing delay. Hence, AiTM attack on open fronthaul interface is possible which results in manipulation of U plane data. The adversary may manipulate RLC and MAC layers of the user plane data to cause DoS attack and/or session redirection attack (e.g. DNS redirection) on legitimate subscribers. Confidentiality and integrity protection requirements are not specified by ORAN alliance for control, user and synchronization (CUS) planes, and those are mandatory for M plane. See clause 6.1 of [2] and clause 5.4 of [3].\r\n\r\nNote: The user plane data in PDCP and above layers remains integrity protected on Fronthaul U plane and this data manipulation attack will not impact any of those data unless PDCP security is also broken by the adversary.\r\n\r\n", - "#### Addendum Name: Layer 2 Redirection of DNS Requests\r\n##### Architecture Segments: Control Plane, User Plane, Roaming\r\n An adversary can manipulate encrypted traffic to achieve redirection of DNS requests sent by the victim UE to the network over the radio interface.\r\n\r\nUsing a fake gNB and fake UE device, the adversary can modify DNS requests the UE sends over the air, even though they are encrypted, if the adversary knows the correct DNS address and there is no integrity protection on user plane data[1]. User plane integrity protections prevent this attack on typical 5G RAN links, however these protections are optional. Alternatively, an adversary may have bid-down the UE as a precondition to achieve the effect.\r\n \r\n", - "#### Addendum Name: Network Interfaces\r\n##### Architecture Segments: Control Plane, User Plane, Roaming\r\n Adversary with access to a non-Service Based Interface (non-SBI) node or an SBI Network Function (NF), or a function on the roaming/interconnect interfaces, may manipulate or spoof user plane and control plane traffic on that interface without integrity protection, towards a DOS or other attacks on the UE or a NF.\r\n\r\nThe following Network interfaces are in the scope of this document.\r\n\r\n1. “Non-SBI” (non-Service Based Interface) network interfaces are within 5G core (e.g. N4) and RAN (e.g. Xn, F1, E1), and between the RAN and the 5G Core (e.g. N2, N3 interfaces). \r\n\r\n2. SBI network interfaces are between core NFs within an operator network; they use REST APIs.\r\n\r\n3. Roaming and interconnect interfaces, including IPX, are between network operators (between SEPPs (N32), between UPFs (N9), or interworking functions like between AMF and MME (N26)).\r\n\r\nUnlike radio communications, within operator RAN and from RAN to core communications do not always employ integrity protection as per standards. If the gNB does not provide integrity protection for control plane (CP) packets sent on the N2/Xn-C/F1-C/E1 interfaces or does not provide user plane (UP) integrity protection for user plane packets sent on the N3/Xn-U/F1-U interfaces, or UPF does not provide integrity protection for user plane packets sent on the N9 interface, then data manipulation (alteration of messages, insertion/spoofing of messages, or replay of legitimate signaling messages) is possible. This may result in DOS. \r\n\r\nThe adversary with access to the SBI links, for example, with control over a middlebox (not including the Service Communication Proxy or SCP), may manipulate or inject spoofed signaling messages if TLS integrity is not enabled or is using a weak algorithm.\r\n \r\nIf an IPX disables JWS signature or uses a weak algorithm for JWS signature, an AiTM may manipulate data over the N32 interface while a UE is roaming.\r\n\r\nSimilarly, if the EPC interworking interface N26 for non-roaming is not integrity protected, all subscriber signaling data may be manipulated by adversary.
