Detailsinfo

A vulnerability was found in Bosch Infotainment System ECU 283C30861E. It has been declared as critical. This vulnerability affects some unknown functionality of the component Bluetooth Stack. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The specific flaw exists within the Bluetooth stack developed by Alps Alpine of the Infotainment ECU manufactured by Bosch. The issue results from the lack of proper boundary validation of user-supplied data, which can result in a stack-based buffer overflow when receiving a specific packet on the established upper layer L2CAP channel. An attacker can leverage this vulnerability to obtain remote code execution on the Infotainment ECU with root privileges. First identified on Nissan Leaf ZE1 manufactured in 2020.

The weakness was presented with PCA Cyber Security Assessment Team. The advisory is available at nissan.co.uk. This vulnerability was named CVE-2025-32062 since 04/03/2025. The exploitation appears to be easy. The attack can only be initiated within the local network. No form of authentication is required for a successful exploitation.
