Integer Overflow Remote Code Execution Vulnerability in Tesla Model 3 VCSEC Module

CVE-2025-2082

What is CVE-2025-2082?

CVE-2025-2082 is a significant vulnerability affecting the VCSEC module of the Tesla Model 3, a widely recognized electric vehicle designed for safety and efficiency. This vulnerability allows attackers situated on the same network to execute arbitrary code on the vehicle without the need for authentication. The risk posed by this vulnerability is critical, as it could allow unauthorized control over essential vehicle functions, potentially compromising user safety and vehicle security.

Technical Details

The vulnerability arises from an integer overflow issue within the VCSEC module, specifically related to how certificate responses from the Tire Pressure Monitoring System (TPMS) are handled. By manipulating these responses, an attacker can trigger an overflow condition that allows them to write arbitrary data to memory. This exploit enables the attacker to execute code in the context of the VCSEC module, which may include sending unauthorized messages to the vehicle’s CAN bus, potentially affecting other systems within the vehicle.

Potential Impact of CVE-2025-2082

1. Unauthorized Code Execution: The primary concern is the ability for network-adjacent attackers to execute arbitrary code on the vehicle, which might be leveraged to override safety features or manipulate vehicle behavior.

2. Compromise of Vehicle Safety: With control over the vehicle's systems, attackers could potentially create hazardous situations for the driver and passengers, significantly impacting user safety on the road.

3. Threat to Overall Vehicle Security: Exploitation of this vulnerability could lead to broader compromises within the vehicle's security architecture, potentially allowing access to sensitive vehicle data or other connected systems, increasing the risk of further attacks.
