CVE-2024-52063Network attack vector

Application corruption or crash via unchecked XML copy

Published Dec 13, 2024 · Updated Feb 7, 2025

Stack buffer overflow in RTI Connext Professional allows remote attackers to corrupt or crash Routing Service via crafted XML type documents. Core Libraries and Routing Service copy XML type data into a stack buffer without enforcing the input length. Remote reachability requires Routing Service remote administration without Security Plugins RTPS protection; local users can instead replace XML configuration files.
