CVE-2024-4548
Published: 06 May 2024
Summary
CVE-2024-4548 is a critical-severity Improper Input Validation (CWE-20) vulnerability in Deltaww Diaenergie. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 2.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
An SQL injection vulnerability affects Delta Electronics DIAEnergie versions 1.10.1.8610 and earlier. The flaw occurs in the CEBC.exe component when it processes a RecalculateHDMWYC message that is parsed into four fields delimited by the tilde character, allowing improper input handling that leads to SQL injection via the fourth field. The issue is tracked under CWE-20 and CWE-89 and carries a CVSS 3.1 base score of 9.8.
An unauthenticated remote attacker can send a crafted message over the network to exploit the vulnerability without requiring user interaction or credentials. Successful exploitation grants the attacker full control over the confidentiality, integrity, and availability of the affected system.
The referenced Tenable advisory TRA-2024-13 provides additional technical details on the vulnerability. The associated EPSS score reached a peak of 0.5355 before receding to its current value of 0.4838.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Directly implements checks on information inputs to reject invalid data before processing.
Penetration testing uses SQL injection payloads against database interfaces, identifying and supporting fixes for SQL injection weaknesses.
Security testing and developer training directly verify and enforce proper input validation, reducing exploitability of injection and malformed-data weaknesses.
Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.
Spam protection mechanisms perform filtering and detection on inbound/outbound messages, directly compensating for missing or weak input validation of unsolicited content.
