Summary

SIDIS Prime versions before 4.0.800 are affected by multiple vulnerabilities in bundled third-party components including OpenSSL, SQLite, and Node.js packages. The vulnerabilities span multiple CWE categories including buffer overflows (CWE-125, CWE-787), inadequate encryption validation (CWE-295), improper input validation (CWE-20), command injection (CWE-78), path traversal (CWE-22), and others. Siemens has released version 4.0.800 to address these issues.

What this means

What could happen

An attacker with network access to SIDIS Prime could exploit these vulnerabilities to execute arbitrary code, modify data, or bypass authentication controls on manufacturing operations systems that depend on SIDIS Prime for configuration or monitoring. This could result in unauthorized changes to production parameters, system downtime, or data loss.

Who's at risk

Manufacturing operations that use Siemens SIDIS Prime for production system configuration, monitoring, or control. This includes facility operators, process engineers, and IT staff responsible for manufacturing execution systems (MES) and industrial automation infrastructure.

How it could be exploited

An attacker on the network segment containing SIDIS Prime could send specially crafted network requests to vulnerable OpenSSL, SQLite, or Node.js libraries running within SIDIS Prime to trigger buffer overflows, authentication bypass, or command injection. Depending on the specific vulnerability exploited, this could lead to remote code execution on the SIDIS Prime system with the privileges of the application process.

Prerequisites

Network access to SIDIS Prime on the port(s) it listens on (typically HTTP/HTTPS)
