CVE-2025-25729

7.5 HIGH

📋 TL;DR

This vulnerability allows attackers to extract hardcoded cleartext credentials from Bosscomm IF740 OBD2 tablets during the update or boot process. Affected systems include Bosscomm IF740 devices with specific firmware and system versions, potentially exposing sensitive authentication information to unauthorized parties.

💻 Affected Systems

Products:
  • Bosscomm IF740 OBD2 Tablet
Versions: Firmware versions: 11001.7078 & v11001.0000; System versions: 6.25 & 6.00
Operating Systems: Embedded/Linux-based automotive system
Default Config Vulnerable: ⚠️ Yes
Notes: All devices with affected firmware versions are vulnerable by default. Requires access during update or boot process.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers gain administrative access to the device, potentially compromising connected vehicle systems, exfiltrating sensitive vehicle data, or using the device as an entry point to broader automotive networks.

🟠

Likely Case

Local attackers with physical or network access extract credentials, gaining unauthorized access to device functions and potentially connected systems.

🟢

If Mitigated

With proper network segmentation and access controls, impact is limited to the isolated device without broader network compromise.

🌐 Internet-Facing: LOW (requires local access to device during update/boot process)
🏢 Internal Only: MEDIUM (internal attackers with physical or network access could exploit)

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires access to the device during specific processes (update or boot). No public exploit code available as of analysis.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check with vendor for updated firmware

Vendor Advisory: Not provided in references

Restart Required: No

Instructions:

1. Contact Bosscomm for updated firmware. 2. Download and verify firmware integrity. 3. Apply update following vendor instructions. 4. Verify credentials are no longer stored in cleartext.

🔧 Temporary Workarounds

Restrict Physical Access

all

Limit physical access to devices to prevent credential extraction during boot/update processes

Network Segmentation

all

Isolate OBD2 devices on separate network segments to limit lateral movement if compromised

🧯 If You Can't Patch

  • Physically secure devices in locked compartments to prevent unauthorized access
  • Implement strict network access controls and monitor for unusual device behavior

🔍 How to Verify

Check if Vulnerable:

Check device firmware version via system settings or vendor-provided tools. If version matches affected range, device is vulnerable.

Check Version:

Check via device system settings or vendor-specific diagnostic tools

Verify Fix Applied:

After patching, verify firmware version is updated and attempt to extract credentials during boot/update (ethical testing only).

📡 Detection & Monitoring

Log Indicators:

  • Multiple failed authentication attempts
  • Unusual device access during boot/update cycles
  • Credential extraction tool execution

Network Indicators:

  • Unexpected network traffic from OBD2 devices
  • Credential-related data exfiltration

SIEM Query:

DeviceType="OBD2" AND (EventType="Authentication_Failure" OR Process="credential_extraction")
