CVE-2022-24313Network attack vector

Unauthenticated code execution via unchecked message length

Published Feb 9, 2022 · Updated Aug 3, 2024

Stack-based buffer overflow in Distributed Data Systems IGSS Data Server 15.0.0.22020 and earlier allows remote attackers to execute code. IGSSDataServer copies user-supplied message data into a fixed-length stack buffer without first validating its length. The process listens on TCP port 12401 by default, requires no authentication, and runs injected code in the server process context.
