CVE-2017-20242Network attack vector

Unauthenticated code execution via crafted packet

Published Aug 4, 2026 · Updated Aug 4, 2026

Stack-based buffer overflow in Keysight IxChariot Endpoint before 9.5.102 allows remote attackers to crash it or execute code via crafted packets. Keysight has not published the affected packet field, parser routine, buffer size, or missing bounds operation that causes the stack overwrite. Network reachability to the unauthenticated endpoint listener is sufficient; successful corruption causes a crash or code execution in the endpoint process.
