Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SC-5 Denial-of-service Protection good match

prevent

Directly protects the system from denial-of-service effects triggered by specially crafted unauthenticated Modbus TCP packets.

SI-10 Information Input Validation good match

prevent

Validates incoming network packet content to reject malformed Modbus TCP packets that cause the device to crash.

SC-7 Boundary Protection good match

prevent

Enforces boundary controls to monitor, filter, or rate-limit traffic to the exposed Modbus TCP service, preventing crafted packets from reaching the vulnerable component.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact

Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.

Why these techniques?

The vulnerability enables remote unauthenticated denial of service via a specially crafted Modbus TCP packet, directly facilitating Endpoint Denial of Service through application or system exploitation.

Confidence: HIGH · MITRE ATT&CK Enterprise v19.0

NVD Description

A denial of service vulnerability exists in the Modbus 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.

Deeper analysisAI

CVE-2024-48882 is a denial-of-service vulnerability in the Modbus TCP functionality of the Socomec DIRIS Digiware M-70 device running version 1.6.9. The issue arises when a specially crafted network packet is processed, leading to a denial of service. Exploitation requires no authentication, as an attacker can trigger the vulnerability by sending a malicious packet directly to the affected component.

A remote attacker with network access to the device can exploit this vulnerability without privileges or user interaction. Successful exploitation results in a denial of service, disrupting availability with a CVSS v3.1 base score of 8.6 (AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H). The changed scope (S:C) indicates potential impact beyond the vulnerable component, classified under CWE-306 (Missing Authentication for Critical Function).

Mitigation details are available in the Cisco Talos Intelligence report (TALOS-2024-2119) and the official Socomec advisory document, which address patches and remediation steps for the DIRIS Digiware M-70.
