Deeper analysis
TOTOLink N600R V5.3c.7159_B20190425 contains a command injection vulnerability, tracked as CVE-2022-28913 and assigned CWE-78, that is reachable through the filename parameter of the /setting/setUploadSetting endpoint. The flaw received a CVSS 3.1 score of 9.8, reflecting network-accessible, unauthenticated exploitation with no user interaction required and full impact on confidentiality, integrity, and availability.
An unauthenticated remote attacker can supply a crafted filename value to the affected endpoint and execute arbitrary operating-system commands on the device. Successful exploitation grants the attacker complete control over the router, enabling actions such as configuration changes, traffic interception, or use of the device as a foothold for further network attacks.
Public references consist of proof-of-concept material hosted on GitHub that demonstrates the injection vector; no vendor advisory or firmware patch information is included in the available sources. The CVE’s EPSS score has remained near 0.10–0.11 since disclosure, indicating moderate but not sharply increasing exploitation interest.
