Operationally, ranked in the top 7.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A CWE-120 buffer copy vulnerability affects the Interactive Graphical SCADA System Data Server versions 15.0.0.22020 and earlier. The flaw permits a stack-based buffer overflow when the server processes a specially crafted network message, potentially allowing remote code execution. The issue carries a CVSS 3.1 score of 9.8 with network attack vector, no required authentication or user interaction, and full impact on confidentiality, integrity, and availability.
An unauthenticated remote attacker can send a malicious message directly to the exposed Data Server service. Successful exploitation results in arbitrary code execution on the affected host, enabling an adversary to take full control of the SCADA system component.
Schneider Electric security advisory SEVD-2022-039-01 and the corresponding Zero Day Initiative report ZDI-22-325 describe the issue and direct users to vendor-supplied patches or configuration guidance for remediation. The EPSS score has remained flat at 0.0777 with no observed upward trajectory after disclosure.
