Summary

AVEVA Enterprise Data Management Web versions 2019 and earlier contain a SQL injection vulnerability (CWE-89) that allows a remote attacker with network access to execute arbitrary SQL commands against the underlying database. Successful exploitation could result in unauthorized access, modification, or deletion of operational data, process configurations, or historical records stored in the system. The vulnerability affects all v2019 and earlier versions; v2019 SP1 is stated as not possible in the advisory, indicating upgrade to a later major release may be required.

What this means
What could happen
An attacker with network access to the SQL database could execute arbitrary SQL commands, potentially modifying or deleting critical operational data or process configurations stored in Enterprise Data Management Web.
Who's at risk
Water utilities and electric power providers using AVEVA Enterprise Data Management Web (eDNA Web) v2019 or earlier for supervisory data collection and reporting should evaluate their exposure. This includes organizations that rely on eDNA Web to manage historical data, operator logs, or process setpoints.
How it could be exploited
An attacker with access to the network segment where Enterprise Data Management Web v2019 or earlier is deployed can send malicious SQL queries directly to the affected device. No authentication or special complexity is required—the SQL injection vulnerability allows commands to be executed against the underlying database.
Prerequisites
  • Network access to the Enterprise Data Management Web server
  • Device running v2019 or earlier (not patched to SP1 or later)
  • Database port accessible from attacker's network location
