VAR-201905-1028
Vulnerability from variot - Updated: 2025-05-01 23:12A CWE-501: Trust Boundary Violation vulnerability on connection to the Controller exists in all versions of the Modicon M580, Modicon M340, Modicon Quantum and Modicon Premium which could cause unauthorized access by conducting a brute force attack on Modbus protocol to the controller. plural Modicon product Exists in a vulnerability related to the leakage of resources to the wrong area.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Schneider Electric Modicon M580 and other products are products of Schneider Electric (France). Schneider Electric Modicon M580 is a programmable automation controller. Schneider Electric Modicon Premium is a large programmable logic controller (PLC) for discrete or process applications. Schneider Electric Modicon Quantum is a large programmable logic controller (PLC) for process applications, high availability and safety solutions.
A buffer overflow vulnerability exists in several Schneider Electric products. Attackers can exploit this vulnerability to gain unauthorized access through brute force. The following products and versions are affected: Schneider Electric Modicon M580 (all versions); Modicon M340 (all versions); Modicon Quantum (all versions); Modicon Premium (all versions)
