CVE-2024-41682 Siemens CVE debrief

CVE-2024-41682 is a medium-severity authentication weakness in Siemens Location Intelligence family products, published August 13, 2024. The vulnerability stems from insufficient enforcement of rate limiting on authentication attempts, enabling unauthenticated remote attackers to conduct brute force attacks against legitimate user credentials. The CVSS 3.1 score of 5.3 reflects network accessibility with low attack complexity and no required privileges or user interaction, resulting in low confidentiality impact. Siemens has released a vendor fix requiring update to version 4.4 or later. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities catalog. Organizations should prioritize patching and implement compensating network-level access controls where immediate patching is not feasible.

Who should care

Organizations operating Siemens Location Intelligence family products in industrial or enterprise environments, particularly those with externally accessible management interfaces. Security teams responsible for ICS/OT infrastructure, identity and access management administrators, and compliance officers monitoring for authentication control weaknesses should prioritize assessment and remediation.

Technical summary

The Siemens Location Intelligence family fails to properly restrict excessive authentication attempts, violating secure authentication design principles. An unauthenticated attacker can exploit this weakness remotely over the network to systematically guess legitimate user passwords without triggering account lockout or rate limiting protections. The vulnerability is classified as CWE-307: Improper Restriction of Excessive Authentication Attempts. Successful exploitation grants the attacker access to authenticated functionality with the compromised user's privileges. The attack requires no user interaction and can be conducted with low complexity. Siemens has addressed this in version 4.4 through implementation of proper authentication attempt restrictions.

Defensive priority

medium

Recommended defensive actions

Update Siemens Location Intelligence family products to version 4.4 or later per vendor guidance
Implement network-level access restrictions to limit exposure of affected authentication interfaces
Monitor authentication logs for anomalous login attempt patterns indicative of brute force activity
Apply defense-in-depth controls per CISA ICS recommended practices for industrial control systems
