ELECOM wireless LAN access point devices use a hard-coded cryptographic key when creating backups of configuration files. An attacker who knows the encryption key can tamper the configuration file of the product, and a victim administrator may be tricked to use a crafted configuration file.

OS command injection vulnerability in ELECOM wireless LAN routers allows a network-adjacent attacker with an administrative privilege to execute arbitrary OS commands by sending a specially crafted request to the product.
