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 vulnerability without size checking 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 specially crafted mathematically reduced data request messages, which can result in remote code execution.
An unauthenticated attacker with network access can send malicious messages to trigger the overflow. Successful exploitation yields full control over the affected server, enabling arbitrary code execution along with impacts to confidentiality, integrity, and availability.
Schneider Electric advisory SEVD-2022-165-01 recommends upgrading IGSS Data Server to version 15.0.0.22170 or later to address the issue. The notice details the affected executable and provides the fixed release that resolves the buffer handling defect.
EPSS for the CVE reached a peak of 0.0594 before receding to the current value of 0.0177.
