Model S: Execution with Unnecessary Privileges

Published Updated By the CyberSecBulletin desk

CVE-2024-6030 is a high-severity execution with unnecessary privileges vulnerability in Model S from Tesla, with a CVSS 3.0 base score of 7.0 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. Affected Model S versions: 2023.44.29. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.17% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

Tesla Model S oFono Unnecessary Privileges Sandbox Escape Vulnerability. This vulnerability allows local attackers to escape the sandbox on affected Tesla Model S vehicles. An attacker must first obtain the ability to execute code within the sandbox on the target system in order to exploit this vulnerability. The specific flaw exists within the oFono process. The process allows an attacker to modify interfaces. An attacker can leverage this vulnerability to bypass the iptables network sandbox. Was ZDI-CAN-23200.

The underlying weakness: Execution with Unnecessary Privileges

The product performs an operation at a privilege level that is higher than the minimum level required, which creates new weaknesses or amplifies the consequences of other weaknesses.

How developers prevent this class of flaw

  • Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
  • Identify the functionality that requires additional privileges, such as access to privileged operating system resources. Wrap and centralize this functionality if possible, and isolate the privileged code as much as possible from other code. Raise privileges as late as possible, and drop them as soon as possible to avoid CWE-271. Avoid weaknesses such as CWE-288 and CWE-420 by protecting all possible communication channels that could interact with the privileged code, such as a secondary socket that is only intended to be accessed by administrators.
