CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This vulnerability is an SQL injection flaw in Siemens SINEC NMS versions prior to V4.0 SP1, specifically exploitable via the getTotalAndFilterCounts endpoint. An authenticated attacker with low privileges can inject malicious SQL commands, which can lead to privilege escalation, allowing the attacker to gain higher access rights than initially permitted. [1]

Impact Analysis

If exploited, this vulnerability allows an attacker with low privileges to execute arbitrary SQL commands, potentially inserting data and escalating their privileges within the system. This can lead to unauthorized access, data manipulation, and compromise of the affected system's integrity and confidentiality. [1]

Detection Guidance

Detection of this vulnerability involves monitoring for SQL injection attempts targeting the getTotalAndFilterCounts endpoint on affected Siemens SINEC NMS versions prior to V4.0 SP1. Since the vulnerability requires authentication with low privileges, reviewing logs for unusual or unauthorized SQL commands or privilege escalation attempts through this endpoint is recommended. Specific detection commands are not provided in the available resources. [1]

Mitigation Strategies

Immediate mitigation steps include updating Siemens SINEC NMS to version V4.0 SP1 or later, as this update remediates the SQL injection vulnerability. Additionally, follow Siemens' general security recommendations such as protecting network access to the affected devices and configuring them according to Siemens' Industrial Security operational guidelines to reduce exposure.
