CVE-2026-78315 Overview
CVE-2026-78315 is a SQL injection vulnerability in Delta Electronics DIAEnergie version v1.11.00.002. The flaw allows an authenticated remote attacker to inject malicious SQL statements through unsanitized input parameters. Successful exploitation can lead to remote code execution on the affected host. DIAEnergie is an industrial energy management system deployed in manufacturing and critical infrastructure environments, which raises the operational impact of this issue. The vulnerability is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).
Critical Impact
An authenticated attacker with low privileges can pivot from SQL injection to remote code execution, compromising the confidentiality, integrity, and availability of the DIAEnergie server.
Affected Products
- Delta Electronics DIAEnergie v1.11.00.002

Technical Details for CVE-2026-78315
Vulnerability Analysis
CVE-2026-78315 exists in the DIAEnergie web application where user-supplied input is concatenated into SQL statements without proper parameterization or sanitization. An authenticated attacker submits crafted parameters that break out of the expected query context and inject arbitrary SQL. Because the underlying database service typically runs with elevated privileges on the DIAEnergie host, the attacker can leverage database features such as xp_cmdshell or file-writing primitives to achieve command execution. This transforms a data-layer bug into full host compromise, allowing the attacker to run arbitrary operating system commands under the database service account.
Root Cause
The root cause is improper neutralization of special elements used in a SQL command [CWE-89]. Input received over HTTP is passed directly into dynamic SQL queries executed against the backend database. The application lacks prepared statements, parameter binding, and allow-list validation, so metacharacters such as single quotes, semicolons, and comment sequences alter the query structure.
Attack Vector
The attack is remote and network-based against the DIAEnergie web interface. The attacker must hold valid low-privilege credentials to reach the vulnerable endpoint. Once authenticated, the attacker sends HTTP requests containing SQL payloads in vulnerable parameters. By chaining SQL injection with database-level command execution features, the attacker escalates to remote code execution on the server hosting DIAEnergie.
No public proof-of-concept has been published. See the Delta Electronics Security Advisory for vendor-specific technical details.
Detection Methods for CVE-2026-78315
Indicators of Compromise
- HTTP requests to DIAEnergie endpoints containing SQL metacharacters such as ', --, ;, UNION SELECT, or WAITFOR DELAY in parameter values
- Database process (for example sqlservr.exe) spawning child processes such as cmd.exe, powershell.exe, or xp_cmdshell invocations
- New or unexpected files written under the DIAEnergie web root or database data directory
- Unusual outbound network connections initiated by the DIAEnergie host to attacker-controlled infrastructure
Detection Strategies
- Inspect DIAEnergie web server logs for parameter values containing SQL syntax and encoded variants
- Enable database audit logging and alert on execution of xp_cmdshell, sp_OACreate, or bulk insert statements from the application account
- Monitor endpoint telemetry for process-tree anomalies where the database service is the parent of shell or scripting interpreters
- Deploy web application firewall (WAF) rules that identify common SQL injection patterns against DIAEnergie URIs
Monitoring Recommendations
- Baseline normal query patterns from the DIAEnergie application account and alert on deviations
- Forward web, database, and endpoint logs to a centralized platform for correlation across the attack chain
- Alert on authentication activity from unusual source IPs or at unusual times for DIAEnergie accounts
How to Mitigate CVE-2026-78315
Immediate Actions Required
- Apply the fixed version of DIAEnergie as directed in the Delta Electronics Security Advisory
- Restrict network access to the DIAEnergie web interface using firewall rules and VPN gating
- Rotate credentials for all DIAEnergie user accounts and the database service account
- Review database and web logs for prior exploitation attempts against vulnerable endpoints
Patch Information
Delta Electronics has published advisory Delta-PCSA-2026-00015 covering SQL injection vulnerabilities in DIAEnergie. Administrators should consult the advisory to identify the fixed release and upgrade paths for v1.11.00.002 and earlier deployments.
Workarounds
- Place DIAEnergie behind a web application firewall with SQL injection signatures enabled
- Disable xp_cmdshell and other command execution features on the backing database instance
- Enforce least-privilege on the database account used by DIAEnergie so it cannot execute operating system commands or write to disk
- Segment the DIAEnergie host into an OT/management VLAN with strict egress controls
