Security readout for executives and security teams
This flaw affects IGSS Definition (Def.exe) versions V15.0.0.21140 and earlier. A malicious WSP file can trigger unsafe parsing, potentially causing data loss or remote code execution. Business risk is highest where IGSS engineering files are exchanged, opened from untrusted sources, or handled on operational technology workstations. Organizations using IGSS Definition (Def.exe) V15.0.0.21140 or earlier are potentially exposed. Practical exposure depends on whether users or systems parse WSP files, especially files received from external, shared, or poorly controlled sources. Treat this as a priority OT workstation risk if IGSS Definition is present. The main urgency is preventing malicious project-file handling while confirming vendor remediation, not responding to known active exploitation based on the supplied evidence. Mitigation focus: Review Schneider Electric advisory SEVD-2021-159-01 for official updates or mitigations.; Inventory IGSS Definition installations and identify versions V15.0.0.21140 or earlier.; Restrict WSP file handling to trusted sources and authorized engineering users..

Out-of-bounds Read
Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
