CVE-2022-32524Public exploitNetwork attack vector

Unauthenticated code execution via unchecked opcode 5 count

Published Jan 30, 2023 · Updated Feb 5, 2025

Stack-based buffer overflow in Schneider Electric IGSS Data Server before 15.0.0.22170 allows remote attackers to execute code via opcode 5 messages. The opcode 5 ONL request handler trusts nItems when calculating memcpy's destination, so crafted time-reduced data is copied beyond the allocated buffer. The service listens on TCP port 12401 without authentication or user interaction, and successful corruption grants code execution in the server process context.
