Quick assessment

Affected
Alpine iLX-F511
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Alpine iLX-F511 的 vCard 解析存在基于栈的缓冲区溢出漏洞，可导致远程代码执行。该漏洞允许处于网络邻近位置的攻击者在受影响的 Alpine iLX-F511 设备上执行任意代码。利用此漏洞需要用户交互，即目标设备必须主动连接至恶意的蓝牙设备。 该具体缺陷存在于 vCard 数据的解析过程中。问题根源在于：在将用户提供的数据复制到固定长度的栈缓冲区之前，未对其进行充分的验证。攻击者可利用此漏洞，以 root 用户权限执行任意代码。此漏洞编号为 ZDI-CAN-29017。

Alpine iLX-F511 vCard Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability
Source: CVE Program / CVE List V5
Vulnerability Description
Alpine iLX-F511 vCard Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected Alpine iLX-F511 devices. User interaction is required to exploit this vulnerability in that the target must connect to a malicious Bluetooth device. The specific flaw exists within the parsing of vCard data. The issue results from the lack of proper validation 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-29017.
