Summary

Alpine iLX-F511 devices are affected by a stack-based buffer overflow in the Android Auto connection handler. The flaw exists because the length of user-supplied data is not validated before it is copied into a fixed-length stack buffer (CWE-121). A physically present attacker can execute arbitrary code in the context of root without authentication.

Description from the CNA

Alpine iLX-F511 Android Auto Connection Handler Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Alpine iLX-F511 devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Android Auto connection handler. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-29016.
