CVE-2017-20241Network attack vector

Unauthenticated code execution via malformed packet

Published Aug 4, 2026 · Updated Aug 4, 2026

Heap-based buffer overflow in Keysight IxChariot Endpoint before 9.5.102 allows remote attackers to crash it or execute arbitrary code. The public record does not identify the packet field, parser, or memory-copy operation that writes beyond the heap allocation. Any network-reachable endpoint accepts the crafted packet without authentication or user interaction, causing a crash or code execution in the endpoint process.
