CVE-2025-40885 Siemens CVE debrief

A SQL injection vulnerability in the Smart Polling functionality of Siemens RUGGEDCOM APE1808 allows authenticated users with limited privileges to execute arbitrary SELECT statements against the application's database. The vulnerability stems from improper input validation on a parameter within the Smart Polling feature. This is a read-only SQL injection—attackers can extract unauthorized data but cannot modify database contents based on the described impact. The CVSS 3.1 score of 5.3 (Medium) reflects the attack complexity requirements (high) and the need for authenticated access with low privileges. The vulnerability was disclosed on August 12, 2025, with the advisory subsequently updated in October 2025 to add this CVE, and again in November 2025 and January 2026 to incorporate remediation guidance. CISA republished the advisory on January 14, 2026, based on Siemens ProductCERT's SSA-978177 advisory.

Who should care

Organizations operating Siemens RUGGEDCOM APE1808 devices in industrial environments, particularly those with external or broadly accessible web management interfaces. Security teams responsible for OT/ICS infrastructure, database administrators managing backend systems for industrial applications, and compliance officers tracking CVE remediation for critical infrastructure assets.

Technical summary

The Smart Polling functionality in Siemens RUGGEDCOM APE1808 fails to properly validate an input parameter, enabling SQL injection. An attacker with authenticated low-privilege access can inject arbitrary SELECT statements to read data from the underlying database management system. The vulnerability is constrained to data exfiltration (no write capabilities described) and requires network access to the web management interface with valid credentials.

Defensive priority

medium

Recommended defensive actions

  • Apply vendor fix by upgrading Nozomi Guardian/CMC to V25.4.0; use CLI rather than Web GUI for the upgrade process due to potential errors
  • Implement network segmentation and use internal firewall features to restrict access to the web management interface
  • Review and audit all accounts with web management interface access, removing unnecessary accounts
  • Contact Siemens customer support to obtain patch and detailed update information
  • Monitor database query logs for anomalous SELECT statements that may indicate exploitation attempts
  • Apply principle of least privilege to all accounts with access to the Smart Polling functionality
