CyberRota Analysis

AI-Generated

The vulnerability allows unauthenticated remote attackers to exploit a stack buffer overflow in COVESA Open1722 versions up to 0.9.2 by sending a specially crafted UDP datagram, which can lead to arbitrary code execution or denial of service. This occurs due to the lack of bounds checking in the avtp_to_can() function, enabling attackers to overwrite adjacent stack memory. Organizations using affected versions of COVESA Open1722 should prioritize patching this vulnerability to mitigate the risk of exploitation.

Original NVD 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.
