Summary

QMS Automotive before V12.39 contains multiple vulnerabilities including malicious code injection, information disclosure, and denial of service. The vulnerabilities stem from improper credential handling (CWE-256, CWE-284), weak cryptography (CWE-319, CWE-316), insufficient input validation (CWE-434, CWE-550), and broken authentication (CWE-347, CWE-922). An attacker with valid credentials could exploit these flaws to modify production data, extract sensitive information, or disable the quality management system. Siemens has released update V12.39 which addresses all identified issues.

What this means
What could happen
An attacker with valid user credentials could inject malicious code, extract sensitive information, or crash the QMS Automotive system, potentially disrupting quality management and production processes at manufacturing facilities.
Who's at risk
Automotive manufacturing facilities and suppliers using Siemens QMS Automotive for quality management and production tracking. This affects quality engineers, production planners, and plant operations staff who rely on QMS for recording test results, managing specifications, and tracking compliance data.
How it could be exploited
An attacker with valid credentials can access the QMS Automotive application over the network and inject malicious code or retrieve sensitive data through multiple vulnerability vectors (code injection, weak cryptography, information disclosure). This could allow the attacker to modify production quality parameters, alter records, or disable the system entirely.
Prerequisites
  • Valid user account credentials for QMS Automotive
  • Network access to the QMS Automotive application server (typically port 80/443 or proprietary ports)
  • QMS Automotive version prior to 12.39
