Vulnerability Title
COVESA Open1722 0.9.2 Stack Buffer Overflow via avtp_to_can() in acf-can-listener
Vulnerability Description
COVESA Open1722 through 0.9.2 contains a stack buffer overflow vulnerability that allows unauthenticated remote attackers to write past the end of a fixed 15-slot stack array by sending a crafted UDP datagram containing more than 15 ACF-CAN messages. The avtp_to_can() function increments its write index without bounding it against the caller-supplied array size, and because the listener accepts datagrams from any sender matching a hardcoded unauthenticated stream ID transmitted in plaintext, attackers can corrupt adjacent stack memory to achieve arbitrary code execution or denial of service.

Vulnerability Title
covesa Open1722 缓冲区错误漏洞
Vulnerability Description
covesa Open1722是covesa组织的一款网络服务器设备。 covesa Open1722 0.9.2及之前版本存在缓冲区错误漏洞,该漏洞源于avtp_to_can()函数在写入时未对调用方提供的数组大小进行边界检查,导致栈缓冲区溢出,可能允许未经身份验证的远程攻击者通过发送包含超过15个ACF-CAN消息的特制UDP数据报破坏相邻栈内存,从而执行任意代码或造成拒绝服务。
