Vulnerabilities

Improper Handling of Case Sensitivity vulnerability in elixir-tesla tesla allows credential leakage to a third-party origin on cross-origin redirects. Tesla.Middleware.FollowRedirects strips security-sensitive headers on cross-origin redirects using a case-sensitive string comparison against a lowercase filter list (@filter_headers ["authorization", "host"]). HTTP header names are case-insensitive per RFC 7230, but Tesla preserves header keys verbatim as supplied by the caller without normalizing case. A header set as {"Authorization", "Bearer …"} (the RFC 7235 canonical casing used by virtually all HTTP libraries and documentation) does not match the lowercase filter entry and is forwarded to the redirect destination. An attacker who can control or influence a Location: response seen by the client (via their own endpoint, a redirect-open upstream, or a compromised origin) receives the bearer token or other Authorization material on the cross-origin request. This issue affects tesla: from 1.4.0 before 1.18.3.

Tesla Wall Connector Content-Length Header Improper Input Validation Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Tesla Wall Connector devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of the HTTP Content-Length header. The issue results from the lack of proper validation of user-supplied data, which can result in memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-26300.

Tesla Model 3 VCSEC Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected Tesla Model 3 vehicles. Authentication is not required to exploit this vulnerability. The specific flaw exists within the VCSEC module. By manipulating the certificate response sent from the Tire Pressure Monitoring System (TPMS), an attacker can trigger an integer overflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the VCSEC module and send arbitrary messages to the vehicle CAN bus. Was ZDI-CAN-23800.

Tesla Model S Iris Modem ql_atfwd Command Injection Code Execution Vulnerability. This vulnerability allows local attackers to execute arbitrary code on affected Tesla Model S vehicles. An attacker must first obtain the ability to execute code on the target system in order to exploit this vulnerability. The specific flaw exists within the ql_atfwd process. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code on the target modem in the context of root. Was ZDI-CAN-23201.

Tesla Model 3 Gateway Firmware Signature Validation Bypass Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected Tesla Model 3 vehicles. An attacker must first obtain the ability to execute privileged code on the Tesla infotainment system in order to exploit this vulnerability. The specific flaw exists within the handling of firmware updates. The issue results from improper error-handling during the update process. An attacker can leverage this vulnerability to execute code in the context of Tesla's Gateway ECU. . Was ZDI-CAN-20734.

In TeslaMate before 1.27.2, there is unauthorized access to port 4000 for remote viewing and operation of user data. After accessing the IP address for the TeslaMate instance, an attacker can switch the port to 3000 to enter Grafana for remote operations. At that time, the default username and password can be used to enter the Grafana management console without logging in, a related issue to CVE-2022-23126.

An issue in Teslamate v1.27.1 allows attackers to obtain sensitive information via directly accessing the teslamate link.

This vulnerability allows local attackers to escalate privileges on affected Tesla vehicles. An attacker must first obtain the ability to execute privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of the wowlan_config data structure. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-17543.

Tesla Model 3 V11.0(2022.4.5.1 6b701552d7a6) Tesla mobile app v4.23 is vulnerable to Authentication Bypass by spoofing. Tesla Model 3's Phone Key authentication is vulnerable to Man-in-the-middle attacks in the BLE channel. It allows attackers to open a door and drive the car away by leveraging access to a legitimate Phone Key.

Certain Tesla vehicles through 2022-03-26 allow attackers to open the charging port via a 315 MHz RF signal containing a fixed sequence of approximately one hundred symbols. NOTE: the vendor's perspective is that the behavior is as intended

TeslaMate before 1.25.1 (when using the default Docker configuration) allows attackers to open doors of Tesla vehicles, start Keyless Driving, and interfere with vehicle operation en route. This occurs because an attacker can leverage Grafana login access to obtain a token for Tesla API calls.

Tesla SolarCity Solar Monitoring Gateway through 5.46.43 has a "Use of Hard-coded Credentials" issue because Digi ConnectPort X2e uses a .pyc file to store the cleartext password for the python user account.

Tesla Model X vehicles before 2020-11-23 have key fobs that accept firmware updates without signature verification. This allows attackers to construct firmware that retrieves an unlock code from a secure enclave chip.

Tesla Model 3 vehicles allow attackers to open a door by leveraging access to a legitimate key card, and then using NFC Relay. NOTE: the vendor has developed Pin2Drive to mitigate this issue

The driving interface of Tesla Model 3 vehicles in any release before 2020.4.10 allows Denial of Service to occur due to improper process separation, which allows attackers to disable the speedometer, web browser, climate controls, turn signal visual and sounds, navigation, autopilot notifications, along with other miscellaneous functions from the main screen.

The renderer process in the entertainment system on Tesla Model 3 vehicles mishandles JIT compilation, which allows attackers to trigger firmware code execution, and display a crafted message to vehicle occupants.

An issue was discovered in Tesla Motors Model S automobile, all firmware versions before version 7.1 (2.36.31) with web browser functionality enabled. The vehicle's Gateway ECU is susceptible to commands that may allow an attacker to install malicious software allowing the attacker to send messages to the vehicle's CAN bus, a Command Injection.
