CVE-2026-46746
Received Received - Intake
Command Injection in SINEC INS via SFTP Upload

Publication date: 2026-06-09

Last updated on: 2026-06-09

Assigner: Siemens AG

Description
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 6). The application does not properly sanitize user input in the /api/sftp/uploadFiles endpoint, allowing the injection of shell command payloads via crafted directory names. These payloads are stored and executed when directory listings are retrieved. This could allow an authenticated remote attacker to execute arbitrary commands on the underlying operating system with the privileges of the affected service user (sinecins).

Executive Summary

This vulnerability exists in SINEC INS versions prior to V1.0 SP2 Update 6. It occurs because the application does not properly sanitize user input in the /api/sftp/uploadFiles endpoint. Specifically, an attacker can inject shell command payloads through crafted directory names. These malicious payloads are stored and later executed when directory listings are retrieved.

As a result, an authenticated remote attacker can execute arbitrary commands on the underlying operating system with the privileges of the service user running SINEC INS (named sinecins).

Impact Analysis

This vulnerability can have serious impacts because it allows an authenticated remote attacker to execute arbitrary commands on the system with the privileges of the affected service user. This could lead to unauthorized access, data manipulation, system compromise, or disruption of services.

Mitigation Strategies

To mitigate the vulnerability in SINEC INS (all versions before V1.0 SP2 Update 6), it is recommended to update the application to version V1.0 SP2 Update 6 or later.
