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.

Buffer overflow vulnerability exists in ELECOM wireless LAN routers, which may allow an unauthenticated attacker to execute arbitrary code.

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.
