Published: 30 January 2023
Summary
CVE-2022-32525 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 14.0% 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 produces a stack-based buffer overflow when the server processes specially crafted alarm data messages, which can result in remote code execution.
An unauthenticated attacker with network access can send malicious alarm messages to trigger the overflow. Successful exploitation grants full control over the affected server, including arbitrary code execution with impacts on 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.
EPSS for the CVE reached a peak of 0.0567 before receding to the current value of 0.0260.
