CVE-2025-11788

Memory corruption via unbounded meter parameter formatting

Published Dec 2, 2025 · Updated Dec 2, 2025

Heap-based buffer overflow in Circutor SGE-PLC1000 and SGE-PLC50 9.0.2 allows remote authenticated users to corrupt memory. ShowSupervisorParameters() passes the user-controlled meter value from GetParameter() to sprintf(), which writes into a fixed-size buffer without a length check. Access to the adjacent-network index.cgi interface and a low-privilege session are required; the overwrite can crash the service or enable code execution.
