Short explanation

The Electronic Delivery Item Inspection Support System (versions 0 <= 4.0.36 affected) contains an improper file access permission flaw that allows low‑privilege local users to modify files in the installation folder, leading to arbitrary code execution. CVSS v3.0 score is 7.8 (HIGH). No official patch has been confirmed (S0).

Why does it matter?

Successful exploitation can give an attacker full control over the system, exposing confidential data and disrupting service availability.

What should be done?

Monitor vendor advisories for patches
Restrict write permissions on the installation directory
Deploy host‑based intrusion detection
Enforce least‑privilege principles
Plan upgrade when a fixed version is released
