CVE-2022-25078Known exploitationNetwork attack vector

Unauthenticated command execution via QUERY_STRING injection

Published Feb 22, 2022 · Updated Aug 3, 2024

OS command injection in the Main function of TOTOLink A3600R firmware 4.1.2cu.5182_B20201102 allows remote attackers to execute commands. The Main function passes attacker-controlled QUERY_STRING content into command execution without neutralizing shell metacharacters. Network access to the router interface is sufficient; successful exploitation runs arbitrary commands with the firmware process privileges and can fully control the device.
