Summary

Multiple vulnerabilities in MDT AutoSave and AutoSave for System Platform (A4SP) allow unauthenticated remote code execution on the Remote MDT Server. The vulnerabilities stem from weak input validation, SQL injection, and improper file handling (CWE-326, CWE-89, CWE-23, CWE-77, CWE-427, CWE-209, CWE-434). An attacker with knowledge of the product's database structure could exploit these flaws to execute arbitrary commands without valid credentials, potentially compromising data integrity and system availability.

What this means
What could happen
An attacker with detailed knowledge of MDT AutoSave's database structure could execute arbitrary code remotely on the Remote MDT Server without needing valid credentials, potentially taking control of the data collection and alarm management system that monitors your facility.
Who's at risk
Water utilities and electric utilities using MDT AutoSave or AutoSave for System Platform (A4SP) for remote data collection, alarm management, and monitoring are affected. This impacts any facility relying on these systems for real-time supervisory data and historical trending.
How it could be exploited
An attacker sends a specially crafted request over the network to the Remote MDT Server, exploiting weak input validation and SQL injection vulnerabilities. If the attacker understands the database schema, they can inject malicious commands that lead to arbitrary code execution on the server, allowing them to modify or delete critical process data or plant alarm configurations.
Prerequisites
  • Network access to the Remote MDT Server (default or non-standard port)
  • Detailed knowledge of MDT AutoSave database structure and architecture
  • No valid user credentials or authentication required
Remotely exploitableNo authentication requiredLow complexity exploitation with detailed product knowledgeNo patch available for some product versionsHigh CVSS score (10.0)Affects data collection and alarm systems critical to operations
