Deeper analysis
TOTOLink N600R firmware version V5.3c.7159_B20190425 contains a command injection vulnerability (CWE-78) that can be triggered through the devicemac parameter supplied to the /setting/setDeviceName endpoint. The flaw received 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 send a crafted HTTP request containing operating-system commands in the affected parameter, resulting in arbitrary command execution on the device with the privileges of the web server process. Successful exploitation grants the attacker the ability to read or modify device configuration, install persistent malware, or pivot into attached networks.
Public references consist solely of proof-of-concept repositories demonstrating the injection; no vendor advisory or firmware patch information is provided. The associated EPSS score has remained near 0.10–0.11 with no material post-disclosure rise.
