Overview<\/strong><\/p>\n

This report provides an in-depth look at the critical vulnerability identified as CVE-2025-9365. This vulnerability affects Fuji Electric’s FRENIC-Loader 4 and poses a significant threat due to its potential for arbitrary code execution. Being a widely used industrial product, the severity and potential impact of this vulnerability<\/a> should not be underestimated.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-9365
\nSeverity: High (7.8 CVSS)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: Required
\nImpact: System compromise<\/a>, potential data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Fuji Electric FRENIC-Loader | 4.0<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit hinges on a deserialization vulnerability present in the file<\/a> import function of FRENIC-Loader 4. An attacker can craft a malicious file which, when imported through a specific window in the application, allows the execution of arbitrary code<\/a>. This is due to the application\u2019s failure to properly validate or sanitize the imported data before processing it.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a conceptual example of how the vulnerability might be exploited. This is a representation of a malicious file that could be used to trigger the vulnerability<\/a>.<\/p>\n

import java.io.*;\nimport java.util.*;\npublic class Exploit{\npublic static void main(String[] args) {\ntry {\nProcessBuilder pb = new ProcessBuilder(\"cmd.exe\", \"\/c\", \"your malicious command\");\nProcess p = pb.start();\n} catch (IOException e) {\ne.printStackTrace();\n}\n}\n}<\/code><\/pre>\n
This Java code would be serialized into a file, which would then be imported into FRENIC-Loader 4. The deserialization vulnerability would allow the execution of the arbitrary code<\/a> contained within the file.<\/p>\n
Mitigation<\/strong><\/p>\n
Users are urged to apply the latest patch provided by the vendor, Fuji Electric, which addresses this vulnerability. As a temporary mitigation measure, users can also employ Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) to detect and prevent attempted exploits. However, these measures are not substitutes for applying the vendor-provided patch.<\/p>\n","protected":false},"excerpt":{"rendered":"
