Deeper analysis
TOTOLink N600R V5.3c.7159_B20190425 contains an OS command injection vulnerability, tracked as CVE-2022-28910 and assigned CWE-78, that is reachable via the devicename parameter in the /setting/setDeviceName endpoint. The flaw carries a CVSS 3.1 base score of 9.8, reflecting network attack vector, low attack complexity, and no required authentication or user interaction.
An unauthenticated remote attacker can supply a crafted devicename value to the affected endpoint and execute arbitrary operating-system commands on the device, resulting in full control over confidentiality, integrity, and availability of the router.
Public proof-of-concept code demonstrating the injection has been published in GitHub repositories, but no vendor advisory or firmware patch information is referenced in the available sources. The associated EPSS score has remained near 0.10 with only a modest recorded peak of 0.11, indicating limited evidence of widespread exploitation interest to date.
