## Technical details

An OS command injection vulnerability (CWE-78) exists in multiple ELECOM wireless LAN routers and access points. The flaw is located in the handling of the 'ping_ip_addr' parameter, where the device fails to properly neutralize special elements before passing them to a system shell. An attacker with administrative privileges (PR:H) can exploit this over the network by sending a specially crafted request to the device's management interface. Successful exploitation allows for arbitrary command execution with the privileges of the web service, potentially leading to full system compromise. Users are advised to update to the latest firmware versions provided by the manufacturer.
