CVE-2024-53684: Socomec Diris M-70 CSRF Vulnerability

CVE-2024-53684 Overview

A cross-site request forgery (CSRF) vulnerability exists in the WEBVIEW-M functionality of Socomec DIRIS Digiware M-70 firmware version 1.6.9. This vulnerability allows an attacker to craft a specially designed HTTP request that can lead to unauthorized access when a victim visits a malicious webpage. The attack leverages the trust relationship between an authenticated user's browser and the vulnerable device's web interface.

Critical Impact
This HIGH severity vulnerability (CVSS 8.8) enables attackers to perform unauthorized actions on Socomec DIRIS Digiware M-70 devices by tricking authenticated users into visiting malicious webpages, potentially compromising confidentiality, integrity, and availability of industrial energy monitoring systems.

Technical Details for CVE-2024-53684

Vulnerability Analysis

CVE-2024-53684 is classified as CWE-352 (Cross-Site Request Forgery), affecting the WEBVIEW-M web interface of Socomec DIRIS Digiware M-70 industrial energy monitoring devices. The vulnerability carries a CVSS v3.1 score of 8.8 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H.

The CVSS metrics indicate:

Attack Vector (AV:N): Network-accessible, meaning attackers can exploit remotely
Attack Complexity (AC:L): Low complexity required for exploitation
Privileges Required (PR:N): No privileges needed by the attacker
User Interaction (UI:R): Requires victim to visit a malicious webpage
Impact: High impact on Confidentiality, Integrity, and Availability

The Exploit Prediction Scoring System (EPSS) indicates a 0.03% probability of exploitation, placing this vulnerability in the 8th percentile as of 2025-12-16.

Root Cause

The vulnerability stems from missing or insufficient anti-CSRF token validation in the WEBVIEW-M web interface. The application fails to properly verify that HTTP requests originate from legitimate user interactions on the authorized web interface. This allows attackers to forge requests that appear to come from authenticated users when their browsers are tricked into making requests to the vulnerable device.

Industrial control system web interfaces like the DIRIS Digiware M-70 often lack modern web security controls, making them particularly susceptible to CSRF attacks. The absence of same-origin request validation, anti-CSRF tokens, or SameSite cookie attributes enables this attack vector.

Attack Vector

The attack exploits the network-accessible WEBVIEW-M functionality through the following mechanism:

An attacker crafts a malicious webpage containing hidden forms or JavaScript that targets the DIRIS M-70 web interface
The attacker socially engineers an authenticated administrator or user to visit the malicious webpage
The victim's browser automatically sends the forged request to the DIRIS M-70 device, including any session cookies
The vulnerable device processes the request as legitimate, executing unauthorized actions with the victim's privileges

The vulnerability allows attackers to potentially modify device configurations, alter monitoring parameters, or perform other administrative actions without proper authorization. In industrial environments where these devices monitor energy systems, unauthorized modifications could have significant operational consequences.

Detection Methods for CVE-2024-53684

Indicators of Compromise

Unexpected configuration changes on DIRIS M-70 devices without corresponding administrator activity
Web server logs showing HTTP requests to administrative endpoints from unusual referrer URLs
Authentication logs indicating session activity from different network locations simultaneously
Audit logs revealing administrative actions performed outside normal operational hours

Detection Strategies

Network monitoring solutions should be configured to detect anomalous traffic patterns targeting the WEBVIEW-M interface. Key detection approaches include:

Network Traffic Analysis: Monitor for HTTP requests to the DIRIS M-70 web interface that originate from external referrer domains. Legitimate administrative actions should typically originate from internal network management systems.

Web Application Firewall (WAF) Rules: Deploy rules that validate the Origin and Referer headers on sensitive requests to the device's web interface. Requests with mismatched or external origins should be flagged.

Log Correlation: Correlate web server access logs with user authentication events. Administrative actions without corresponding interactive login sessions may indicate CSRF exploitation.

Monitoring Recommendations

Organizations operating Socomec DIRIS Digiware M-70 devices should implement continuous monitoring of device configurations and administrative activities. Consider deploying network segmentation to isolate industrial control devices from general-purpose networks. Enable comprehensive logging on the WEBVIEW-M interface and forward logs to a centralized SIEM solution for correlation and alerting. Establish baseline behavior profiles for administrative access patterns to detect deviations that may indicate compromise.

How to Mitigate CVE-2024-53684

Immediate Actions Required

Review Socomec's official security advisory for firmware updates addressing CVE-2024-53684
Implement network segmentation to isolate DIRIS M-70 devices from untrusted networks
Restrict web interface access to authorized management workstations only
Ensure administrators close browser sessions and clear cookies after managing devices
Consider disabling the WEBVIEW-M web interface if not operationally required

Patch Information

Socomec has released security advisories addressing this vulnerability. Administrators should consult the following resources for patch and remediation guidance:

Contact Socomec support for firmware update availability and installation procedures specific to your deployment environment.

Workarounds

If immediate patching is not feasible, implement defense-in-depth measures to reduce exposure:

Network-level mitigations should restrict access to the WEBVIEW-M interface to trusted management networks only. Configure firewall rules to allow access from specific IP addresses or subnets used for device administration. Deploy a reverse proxy with CSRF protection capabilities in front of the device interface if direct firmware updates are not available.

User-level mitigations include instructing administrators to use dedicated browser profiles or private browsing sessions when accessing the DIRIS M-70 web interface. Administrators should avoid visiting external websites while authenticated to industrial control device interfaces. Implementing strong network access controls and VPN requirements for remote administration adds additional protection layers.
