## Technical details

An OS command injection vulnerability (CWE-78) exists in the 'Restore Settings' functionality of several ELECOM wireless LAN routers and access points. The flaw stems from improper neutralization of special elements within the settings restoration process, allowing an attacker to inject and execute arbitrary OS commands. Exploitation requires the attacker to be authenticated with high privileges (administrative access) to the device's web-based management interface. Successful exploitation grants the attacker full control over the underlying operating system. Users are advised to update their firmware to the latest available versions provided by the vendor.
