Tesla Model 3 VCSEC Vulnerability Lets Hackers Run Arbitrary Code

A high security flaw in Tesla’s Model 3 vehicles, disclosed at the 2025 Pwn2Own hacking competition, allows attackers to execute malicious code remotely via the vehicle’s Tire Pressure Monitoring System (TPMS).

The vulnerability, now patched, highlights growing risks in automotive cybersecurity.

Detail	Description
CVE ID	CVE-2025-2082
CVSS Score	7.5 (High) – Adjacent Network Attack Vector
Affected Vehicles	Tesla Model 3 (pre-firmware 2024.14)
Impact	Full code execution on VCSEC module, CAN bus control
Fix Released	Tesla Firmware Version 2024.14
Credited Researchers	Synacktiv (Thomas Imbert, Vincent Dehors, David Berard)

Technical Breakdown

The vulnerability stems from an integer overflow in the Vehicle Control System Electronic Controller (VCSEC), a module managing security and vehicle communications.

By sending manipulated certificate responses via the TPMS-a wireless system tracking tire pressure-attackers could trigger memory corruption.

This grants control over the VCSEC, enabling unauthorized commands to the CAN bus, which governs critical functions like braking and acceleration.

Notably, exploitation requires proximity (e.g., Bluetooth/Wi-Fi range) but no authentication, making it accessible to determined attackers.

The flaw was uncovered by cybersecurity firm Synacktiv during Pwn2Own 2025, a premier hacking contest. Tesla addressed the issue in October 2024 via an over-the-air firmware update (2024.14).

Full details were released publicly on April 30, 2025, following coordinated disclosure.

Successful exploitation could:

• Disable safety features (e.g., airbags, collision alerts).
• Manipulate driving functions (steering, acceleration).
• Expose sensitive vehicle data.

While no real-world attacks have been reported, the breach underscores the dangers of connected car systems.

“This isn’t just about unlocking doors-it’s about controlling the vehicle’s core systems,” noted Synacktiv researcher Thomas Imbert.

Tesla rolled out the patch silently in 2024, adhering to its standard protocol for security updates. Owners must manually install Firmware 2024.14 via:

1. Tap Software in the car’s touchscreen.
2. Select Install Update if available.

Vehicles with automatic updates enabled likely already have the fix.

Expert Recommendations

• Update Immediately: Ensure firmware is at least 2024.14.
• Monitor Networks: Avoid connecting to public/untrusted Wi-Fi.
• Stay Informed: Enable Tesla’s security notifications.

As vehicles grow smarter, their attack surfaces expand. This incident reinforces the need for robust automotive cybersecurity practices.

Tesla owners are urged to verify their firmware version and apply updates promptly to safeguard against evolving threats.
