User InteractionNone needed
Summary

Samsung Data Management Server version 1.4.2 and earlier contains an SQL injection vulnerability (CWE-89) in its input validation. The vulnerable input fields allow unauthenticated attackers to inject SQL commands directly into database queries. This could allow an attacker to read, modify, or delete data in the server's database. No vendor patch is available for this product.

What this means
What could happen
An attacker with network access could execute SQL injection attacks on the Data Management Server, potentially reading, modifying, or deleting critical plant data stored in the database.
Who's at risk
Water utilities and municipal electric operators rely on data management servers to log, store, and retrieve historical process data, alarms, and system configurations. An SQL injection vulnerability affects any organization using Samsung Data Management Server version 1.4.2 or earlier, directly impacting the integrity and confidentiality of operational data.
How it could be exploited
An attacker sends a crafted HTTP request containing SQL injection payload to the Data Management Server's input fields. The server fails to properly sanitize the input before passing it to the SQL database, allowing the attacker to execute arbitrary SQL commands to extract or manipulate process data, configurations, or alarms stored in the database.
Prerequisites
  • Network access to the Data Management Server on its service port (typically HTTP/HTTPS)
  • No authentication required to exploit the vulnerable input fields

Remediation & Mitigation
0/4
Do now
0/2
WORKAROUNDRestrict network access to the Data Management Server using firewall rules; only permit connections from trusted engineering workstations and SCADA systems that legitimately require database access
HARDENINGDisable or limit access to any web-facing input fields on the Data Management Server if not actively required for operations
Schedule — requires maintenance window
0/1

Patching may require device reboot — plan for process interruption

HARDENINGMonitor database access logs and SQL queries for suspicious patterns or injection attempts
