CVE-2025-14816: CWE-317 Cleartext Storage of Sensitive Information in GUI in Mitsubishi Electric Corporation GENESIS64
CVE-2025-14816 is a critical vulnerability in Mitsubishi Electric GENESIS64 and related products up to versions 10. 97. 3 (and 11. 02 for some) that involves cleartext storage of SQL Server credentials in the GUI of the Hyper Historian Splitter feature. A local attacker with low privileges can access these credentials if SQL Server authentication is used, potentially allowing unauthorized access to the SQL Server. This could lead to data disclosure, tampering, destruction, or denial-of-service conditions on the affected system. The vulnerability has a CVSS 4. 0 score of 9. 3, indicating high impact and exploitability. No official patch or remediation guidance is currently provided by the vendor, and no known exploits are reported in the wild.

The vulnerability is classified under CWE-317 (Cleartext Storage of Sensitive Information) and has a critical CVSS 4.0 score of 9.3. The vendor has not published an official fix or remediation at this time.
Potential Impact
An attacker with local access and low privileges can obtain SQL Server credentials displayed in cleartext in the GUI, allowing unauthorized access to the SQL Server. This can result in disclosure, tampering, or destruction of data, and potentially cause denial-of-service conditions on the affected system. The impact is critical due to the high CVSS score and the potential for significant data compromise and service disruption.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict local access to trusted users only and avoid using SQL Server authentication where possible. Monitor for vendor updates regarding patches or mitigations specific to this vulnerability.
