The Iec104 Project maintains a niche implementation of the IEC 60870-5-104 protocol, a critical industrial control system (ICS) standard used in power systems and grid automation, where a narrow product footprint nonetheless sits in high-consequence operational environments. Observed vulnerabilities cluster around memory-safety issues, specifically NULL-pointer dereferences and out-of-bounds writes, reflecting the low-level protocol parsing demands of ICS communication stacks. Current severity, exploitation activity, and exposure counts are shown alongside this summary.
