Summary

SIMATIC Energy Manager (Basic and PRO versions before V7.3 Update 1) contains multiple vulnerabilities (CWE-732 file permissions, CWE-427 uncontrolled search path, CWE-502 deserialization) that allow local privilege escalation, local code execution, and remote code execution.

What this means
What could happen
An attacker could gain elevated privileges or execute arbitrary code on the Energy Manager server, potentially allowing them to modify energy consumption data, disrupt power monitoring and control functions, or use the system as a foothold to attack connected electrical infrastructure.
Who's at risk
Energy utilities and industrial sites running SIMATIC Energy Manager for power consumption monitoring and control. This includes municipal electric utilities, industrial facilities with onsite power management, and any organization using Siemens energy management software for facility operations.
How it could be exploited
An attacker with local access to the Energy Manager system could exploit weak file permissions or search path vulnerabilities to execute code with elevated privileges. Alternatively, an attacker with network access could send a malicious serialized object to trigger remote code execution if the application deserializes untrusted data.
Prerequisites
  • - For local exploitation: local user access to the Energy Manager server - For remote exploitation: network access to the Energy Manager application ports - Specific configuration details not mentioned in advisory; may require specific inputs or conditions
