CVE-2024-4548 in DIAEnergie
Summary
by MITRE • 05/06/2024
An SQLi vulnerability exists in Delta Electronics DIAEnergie v1.10.1.8610 and prior when CEBC.exe processes a 'RecalculateHDMWYC' message, which is split into 4 fields using the '~' character as the separator. An unauthenticated remote attacker can perform SQLi via the fourth field.

The vulnerability identified as CVE-2024-4548 represents a critical SQL injection flaw within Delta Electronics DIAEnergie software version 1.10.1.8610 and earlier releases. This security weakness manifests specifically when the CEBC.exe component processes a 'RecalculateHDMWYC' message, creating a pathway for malicious actors to manipulate database operations through carefully crafted input. The software architecture processes incoming messages by splitting them into four distinct fields using the tilde character '~' as the primary delimiter, establishing a structured communication protocol that inadvertently introduces the attack vector.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the message processing pipeline. When the fourth field of the 'RecalculateHDMWYC' message is processed, the system fails to properly escape or validate user-supplied data before incorporating it into SQL query constructions. This omission allows an unauthenticated remote attacker to inject malicious SQL payloads directly through the fourth field, bypassing normal authentication mechanisms and authorization controls. The vulnerability operates at the application layer and can be exploited without requiring any prior access credentials or privileged context.
The operational impact of this SQL injection vulnerability extends beyond simple data exfiltration, potentially enabling full database compromise and unauthorized administrative access. Attackers could leverage this weakness to execute arbitrary database commands, access sensitive operational data, modify system configurations, or establish persistent backdoors within the energy management infrastructure. Given that DIAEnergie is designed for industrial energy monitoring and control systems, such exploitation could result in significant operational disruptions, data integrity compromises, and potential safety hazards within industrial environments. The vulnerability affects the core functionality of energy data processing and system recalculations, making it particularly dangerous for critical infrastructure deployments.
Mitigation strategies for CVE-2024-4548 should prioritize immediate software updates from Delta Electronics to address the identified SQL injection flaw. Organizations should implement network segmentation to limit access to affected systems and deploy web application firewalls to monitor and filter suspicious SQL injection patterns. Input validation measures must be strengthened to ensure all message fields undergo proper sanitization before database processing occurs. The vulnerability aligns with CWE-89 which specifically addresses SQL injection weaknesses, and could potentially map to ATT&CK technique T1190 for exploitation of remote services and T1071.3 for application layer protocols. Security teams should also conduct comprehensive vulnerability assessments of their industrial control systems to identify similar implementation flaws and establish robust monitoring procedures for detecting anomalous database access patterns.
