TITLE

Socomec DIRIS Digiware M-70 Denial-of-Service Vulnerability (CNVD-2025-30459)

Trust: 0.6

sources: CNVD: CNVD-2025-30459

DESCRIPTION

A denial of service vulnerability exists in the Modbus TCP and Modbus RTU over TCP functionality of Socomec DIRIS Digiware M-70 1.6.9. A specially crafted series of network requests can lead to a denial of service. An attacker can send a sequence of unauthenticated packets to trigger this vulnerability.An attacker can trigger this denial-of-service condition by sending a single Modbus TCP message to port 503 using the Write Single Register function code (6) to write the value 1 to register 4352. This action changes the Modbus address to 15. After this message is sent, the device will be in a denial-of-service state. The Socomec DIRIS Digiware M-70 is a communication gateway device that serves as the access point for the DIRIS Digiware system, integrating 24VDC power supply and communication functions into a single unit. An attacker could exploit this vulnerability to cause a denial-of-service attack
