CVE-2022-32529
Published: 30 January 2023
Summary
CVE-2022-32529 is a critical-severity Classic Buffer Overflow (CWE-120) vulnerability in Schneider-Electric Interactive Graphical Scada System. Its CVSS base score is 9.8 (Critical).
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 stack-based buffer overflow vulnerability classified as CWE-120 exists in the IGSS Data Server component IGSSdataServer.exe. It affects Schneider Electric IGSS versions prior to V15.0.0.22170 and stems from missing bounds checks when processing log data request messages, which can lead to remote code execution. The flaw carries a CVSS 3.1 score of 9.8 reflecting network attackability without authentication or user interaction.
An unauthenticated remote attacker can send specially crafted log data request messages to the IGSS Data Server and trigger the overflow to execute arbitrary code on the affected system. Successful exploitation grants full control over the server process, enabling data theft, system compromise, or further lateral movement within industrial control environments.
Vendor advisories from Schneider Electric, referenced in SEVD-2022-165-01, direct users to upgrade IGSS Data Server to version 15.0.0.22170 or later to address the issue.
EPSS scores for this CVE rose from low values after disclosure to a peak of 0.0690 on 2026-01-13 before receding to the current 0.0177, indicating a period of increased exploitation interest that warrants renewed attention.
