Siemens has identified the following specific workarounds and mitigations that customers can apply to reduce the risk:
Product-specific remediations or mitigations can be found in the section
Affected Products and Solution.
Please follow the General Security Recommendations.
As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity
The vulnerability classification has been performed by using the CVSS scoring system in version 3.1 (CVSS v3.1) (https://www.first.org/cvss/). The CVSS environmental score is specific to the customer’s environment and will impact the overall CVSS score. The environmental score should therefore be individually defined by the customer to accomplish final scoring.
An additional classification has been performed using the CWE classification, a community-developed list of common software security weaknesses. This serves as a common language and as a baseline for weakness identification, mitigation, and prevention efforts. A detailed list of CWE classes can be found at: https://cwe.mitre.org/.
A SQL Injection vulnerability in Nozomi Networks Guardian and CMC, due to improper input validation in certain parameters used in the Query functionality, allows an authenticated attacker to execute arbitrary SQL queries on the DBMS used by the web application. Authenticated users can extract arbitrary information from the DBMS in an uncontrolled way.

CWE | CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') |
A SQL Injection vulnerability in Nozomi Networks Guardian and CMC, due to improper input validation in certain fields used in the Asset Intelligence functionality of our IDS, may allow an unauthenticated attacker to execute arbitrary SQL statements on the DBMS used by the web application by sending specially crafted malicious network packets.
Malicious users with extensive knowledge on the underlying system may be able to extract arbitrary information from the DBMS in an uncontrolled way, or to alter its structure and data.

CWE | CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') |
A Denial of Service (Dos) vulnerability in Nozomi Networks Guardian and CMC, due to improper input validation in certain fields used in the Asset Intelligence functionality of our IDS, allows an unauthenticated attacker to crash the IDS module by sending specially crafted malformed network packets.
During the (limited) time window before the IDS module is automatically restarted, network traffic may not be analyzed.
