Critical CSRF Vulnerability Exposes Socomec DIRIS Digiware M-70: CVE-2024-53684

by

Overview

A high-severity Cross-Site Request Forgery (CSRF) vulnerability, identified as CVE-2024-53684, has been discovered in the WEBVIEW-M functionality of Socomec DIRIS Digiware M-70 version 1.6.9. This vulnerability allows an attacker to execute unauthorized actions on behalf of an authenticated user, potentially leading to significant security breaches.

Technical Details

The vulnerability exists due to insufficient CSRF protection within the WEBVIEW-M component. An attacker can craft a malicious HTML page containing requests that, when visited by an authenticated user, will be executed by the user’s browser as if they originated from the user themselves. This allows the attacker to potentially modify settings, execute commands, or perform other administrative tasks without the user’s knowledge or consent.

Specifically, a specially crafted HTTP request targeting the vulnerable endpoint can trigger unintended actions. The lack of proper token validation or other CSRF defenses makes the system susceptible to this type of attack.

CVSS Analysis

The Common Vulnerability Scoring System (CVSS) score for CVE-2024-53684 is 7.5 (HIGH). This score reflects the severity of the vulnerability, taking into account factors such as the ease of exploitation, potential impact, and required privileges.

  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N

Possible Impact

Successful exploitation of this CSRF vulnerability could have severe consequences, including:

  • Unauthorized Configuration Changes: An attacker could modify device settings, potentially disrupting operations or compromising security.
  • Data Manipulation: Sensitive data monitored or controlled by the DIRIS Digiware M-70 could be altered or exposed.
  • Denial of Service: Attackers might be able to render the device unusable, impacting critical monitoring or control functions.
  • Privilege Escalation: While not a direct result, successful unauthorized configuration changes could lead to escalated privileges or access to sensitive resources.

Mitigation or Patch Steps

Socomec has released a security advisory and likely a patch to address this vulnerability. Immediate action is required to protect affected systems.

  1. Apply the Patch: Download and install the latest firmware update for your Socomec DIRIS Digiware M-70 devices from the official Socomec website.
  2. Monitor Network Traffic: Implement network monitoring solutions to detect suspicious activity and potential exploitation attempts.
  3. Educate Users: Train users to be cautious about clicking links or visiting untrusted websites, as these could be used to launch CSRF attacks.
  4. Implement Web Application Firewall (WAF): Use a WAF solution to filter malicious requests and block potential CSRF attacks.
  5. Review Access Controls: Ensure that access controls are properly configured and that users only have the necessary permissions to perform their tasks.
