CVE-2024-41907 Siemens CVE debrief

CVE-2024-41907 is a medium-severity vulnerability affecting Siemens SINEC Traffic Analyzer (6GK8822-1BG01-0BA0), published on 2024-08-13. The web server component lacks general HTTP security headers, increasing susceptibility to clickjacking attacks where an attacker could trick users into interacting with hidden interface elements. The CVSS 3.1 score of 4.2 (AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N) reflects network attack vector with high complexity, requiring user interaction but no privileges. Siemens has released version 2.0 or later to address this issue. As an industrial control system component, this vulnerability carries operational technology risk where successful clickjacking could lead to unauthorized configuration changes or information disclosure.

Vendor: Siemens
Product: SINEC Traffic Analyzer (6GK8822-1BG01-0BA0)
CVSS: MEDIUM 4.2
CISA KEV: Not listed in stored evidence
Original CVE published: 2024-08-13

Who should care

Organizations operating Siemens SINEC Traffic Analyzer in industrial network environments, OT security teams responsible for network monitoring infrastructure, and administrators managing web-accessible industrial control system components.

Technical summary

The SINEC Traffic Analyzer web server does not implement standard HTTP security headers including X-Frame-Options and Content-Security-Policy frame-ancestors directives. This configuration gap allows the application to be embedded in malicious frames, enabling clickjacking attacks where user actions are redirected to attacker-controlled functionality. The vulnerability requires user interaction and network access but no authentication, with potential impacts including low confidentiality and integrity compromise.

Defensive priority

medium

Recommended defensive actions

Update SINEC Traffic Analyzer to version 2.0 or later per vendor guidance
Implement Content-Security-Policy frame-ancestors directive and X-Frame-Options header as defense-in-depth measures
Review web application security configurations for missing security headers
Apply network segmentation to limit exposure of industrial control system web interfaces
Monitor for unauthorized configuration changes that could indicate successful clickjacking exploitation
