CVE-2026-89205 · Severity: medium · CVSS 6.3 · Published 2026-10-13

RUGGEDCOM CROSSBOW is a secure access management solution used to provide controlled access to industrial network devices in compliance with regulatory standards. Versions prior to V6.0 contain multiple vulnerabilities including authorization bypasses and SQL injection flaws that allow authenticated attackers to escalate privileges, retrieve administrative credentials, execute unauthorized operations, and potentially cause service disruptions. An attacker with minimal privileges could compromise the entire system's confidentiality, integrity, and availability.

## How to fix

- Fixed in V6.0 or later

Siemens recommends protecting network access to devices with appropriate mechanisms and configuring the environment according to Siemens operational guidelines for Industrial Security to minimize exposure.

## Technical details

The product fails to properly validate and sanitize user input in multiple areas including facility names (bulk import/export), notification conditions, firmware upload filenames, and custom file labels—leading to SQL injection attacks (CWE-89). Additionally, inadequate authorization checks on database queries and device operations allow authenticated attackers to bypass access controls and retrieve sensitive credentials (CWE-639). Network and local attack vectors are possible with low complexity; the vulnerabilities require authentication but not elevated privileges in most cases.

## Affected products

- Siemens RUGGEDCOM CROSSBOW All versions < V6.0
