Operationally, ranked in the top 16.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A CWE-120 buffer copy without checking size of input vulnerability affects the IGSS Data Server component IGSSdataServer.exe in versions prior to V15.0.0.22170. The flaw permits a stack-based buffer overflow when the server processes incoming messages, carrying a CVSS 3.1 score of 9.8 that reflects network accessibility without credentials or user interaction.
An unauthenticated attacker can exploit the issue by sending specially crafted time reduced data messages to the server, achieving remote code execution with full control over the affected process and potentially the underlying host.
Vendor advisory SEVD-2022-165-01 from Schneider Electric addresses the flaw and directs users to upgrade IGSS Data Server to version 15.0.0.22170 or later. The associated EPSS score rose from low values to a peak of 0.0690 before receding to the current 0.0177, indicating a period of increased exploitation interest after disclosure.
