Description
A Resource Exhaustion issue was discovered in Schneider Electric Modicon M340 PLC BMXNOC0401, BMXNOE0100, BMXNOE0110, BMXNOE0110H, BMXNOR0200H, BMXP341000, BMXP342000, BMXP3420102, BMXP3420102CL, BMXP342020, BMXP342020H, BMXP342030, BMXP3420302, BMXP3420302H, and BMXP342030H. A remote attacker could send a specially crafted set of packets to the PLC causing it to freeze, requiring the operator to physically press the reset button on the PLC in order to recover.
