CVE-2023-37563
ELECOM wireless LAN routers are vulnerable to sensitive information exposure, which allows a network-adjacent unauthorized attacker to obtain sensitive information.
Does this matter?
Lower severity and a low EPSS score (0.34%). Track it; it rarely justifies an emergency change on its own.
