Remote code execution via unchecked opcode item count
Published Jan 30, 2023 · Updated Feb 5, 2025
Stack buffer overflow in Schneider Electric IGSS Data Server before 15.0.0.22170 allows remote attackers to execute arbitrary code. The opcode 2 appendRequest path trusts an attacker-controlled item count when calculating a memcpy destination, writing past the request buffer. No authentication or user interaction is required; a crafted online-data request can crash the service or enable code execution.
