CVE-2025-54848
HighCVSS 7.5Exploitation Probability (EPSS)
Low risk34th percentile - higher than 34% of all known CVEs
Summary
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 sequence of unauthenticated Modbus TCP messages using the Write Single Register function code (6) sent to port 502 can put the device into a persistent denial-of-service state.
Risk Assessment
An attacker can remotely disable the device without authentication, potentially crippling monitoring and control of the electrical installation.
Recommendation
Block access to port 502 from untrusted networks, apply OT network segmentation, and urgently deploy the vendor patch.

A denial of service vulnerability exists in the Modbus TCP and Modbus RTU over TCP USB Function functionality of Socomec DIRIS Digiware M-70 1.6.9. A specially crafted network packet can lead to denial of service. An attacker can send an unauthenticated packet to trigger this vulnerability. This vulnerability is specific to the malicious message sent via Modbus RTU over TCP on port 503.
- CVE-2025-55221High
A denial of service vulnerability exists in the Modbus TCP and Modbus RTU over TCP USB functionality of Socomec DIRIS Digiware M-70 1.6.9. A specially crafted network packet sent without authentication to port 502 can cause a denial of service.
- CVE-2025-54851High
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 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.
- CVE-2025-54850High
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, using the Write Single Register function code (6) on port 503.
- CVE-2025-54849High
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 network request can lead to a denial of service. An attacker can send a single Modbus TCP message to port 502 using the Write Single Register function code (6) to write the value 1 to register 4352, changing the Modbus address to 15 and causing a denial-of-service state.
- CVE-2025-26858High
A buffer overflow vulnerability exists in the Modbus TCP functionality of Socomec DIRIS Digiware M-70 1.6.9. Specially crafted network packets can lead to denial of service. An attacker can send a sequence of unauthenticated packets to trigger this vulnerability.
- CVE-2025-23417High
A denial of service vulnerability exists in the Modbus RTU over TCP functionality of Socomec DIRIS Digiware M-70 1.6.9. A specially crafted network packet can lead to denial of service. An attacker can send an unauthenticated packet to trigger this vulnerability.
- CVE-2025-20085High
A denial of service vulnerability exists in the Modbus RTU over TCP functionality of Socomec DIRIS Digiware M-70 1.6.9. A specially crafted network packet can lead to denial of service and weaken credentials resulting in default documented credentials being applied to the device.
Original NVD description (English source)
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 sequence of Modbus TCP messages to port 502 using the Write Single Register function code (6). The attack sequence begins with a message to register 58112 with a value of 1000, indicating that a configuration change will follow. Next, a message is sent to register 29440 with a value corresponding to the new Modbus address to be configured. Finally, a message to register 57856 with a value of 161 commits the configuration change. After this configuration change, the device will be in a denial-of-service state.
