CVE-2021-20853

What is CVE-2021-20853?

ELECOM LAN routers, specifically the WRH-733GBK and WRH-733GWH models with firmware version 1.02.9 and earlier, are susceptible to a command injection vulnerability. This allows an attacker who has network access with administrative privileges to execute arbitrary operating system commands, potentially leading to unauthorized access and manipulation of the router's system. Network administrators should take immediate action to secure affected devices against this exploit.
