Remote service interruption via out-of-bounds write
Published Aug 31, 2022 · Updated Apr 16, 2025
Out-of-bounds write in Moxa NPort 5110 firmware 2.10 allows remote attackers to make the device unresponsive via network traffic. Moxa and CISA identify the memory-boundary failure but have not disclosed the affected parser, protocol message, or unchecked length operation. No credentials or user interaction are required; successful exploitation interrupts device availability without reported data disclosure or modification.
