CVE-2024-6032
📋 TL;DR
This vulnerability allows local attackers with initial code execution on Tesla Model S vehicles to escalate privileges and execute arbitrary commands as root on the Iris modem. It affects Tesla Model S vehicles with vulnerable modem firmware. Attackers must first compromise the vehicle's system to exploit this flaw.
💻 Affected Systems
- Tesla Model S
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full root compromise of the vehicle's Iris modem allowing complete control over modem functions, potential vehicle tracking, communication interception, and lateral movement to other vehicle systems.
Likely Case
Privilege escalation from a compromised user account to root on the modem, enabling persistence, data exfiltration, and further system manipulation.
If Mitigated
Limited impact due to proper access controls preventing initial code execution on the vehicle system.
🎯 Exploit Status
Requires initial code execution on the target system; ZDI advisory suggests the vulnerability is being actively addressed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not publicly specified; Tesla should release firmware updates
Vendor Advisory: https://www.zerodayinitiative.com/advisories/ZDI-25-264/
Restart Required: Yes
Instructions:
1. Check for Tesla vehicle firmware updates via the vehicle's touchscreen or Tesla mobile app. 2. Install any available security updates. 3. Restart the vehicle to apply changes.
🔧 Temporary Workarounds
Restrict physical and network access
allPrevent unauthorized physical or network access to vehicle systems to block initial compromise required for exploitation.
🧯 If You Can't Patch
- Isolate vehicle systems from untrusted networks and devices.
- Implement strict access controls to prevent unauthorized code execution on vehicle systems.
🔍 How to Verify
Check if Vulnerable:
Check vehicle firmware version against Tesla's security bulletins; monitor for unusual modem process activity.
Check Version:
Check firmware version via Tesla vehicle touchscreen: Controls > Software > Additional Vehicle Information
Verify Fix Applied:
Verify firmware has been updated to a version after the patch release date; check that ql_atfwd process properly validates input.
📡 Detection & Monitoring
Log Indicators:
- Unusual command execution from ql_atfwd process
- Suspicious system calls originating from modem subsystem
Network Indicators:
- Anomalous modem communication patterns
- Unexpected data exfiltration from vehicle
SIEM Query:
Process execution where parent_process contains 'ql_atfwd' AND command_line contains special characters or shell metacharacters
