AI-suggested
To mitigate CVE-2026-28267, organizations should first verify the version of i-フィルター 10 in use and upgrade to version 10.02.00 or later once available. In the absence of an official patch, administrators should manually audit and correct file and directory permissions for the system and backup directories used by the software, ensuring that only administrative accounts have write access. Implementing strict access control lists (ACLs) and leveraging Windows security policies to restrict non-administrative user permissions can reduce risk. Additionally, monitoring file integrity in these directories with endpoint detection and response (EDR) tools can help detect unauthorized changes. Limiting local user privileges and enforcing the principle of least privilege across the environment will further reduce the attack surface. Finally, educating users about the risks of local privilege misuse and maintaining robust internal security controls will help prevent exploitation.
Description
Multiple i-フィルター products are configured with improper file access permission settings. Files may be created or overwritten in the system directory or backup directory by a non-administrative user.
