Description
Sony XAV-AX5500 CarPlay TLV Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Sony XAV-AX5500 devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the Apple CarPlay protocol. 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 the device. Was ZDI-CAN-23238

Weakness
| Weakness | Name | Description |
|---|---|---|
| CWE-120 | Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') | The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. |
| CWE-121 | Stack-based Buffer Overflow | 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). |
