Operationally, ranked in the top 9.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
TOTOLink A3600R firmware version V4.1.2cu.5182_B20201102 contains a command-injection flaw (CWE-78) inside the Main function. Untrusted input supplied through the QUERY_STRING parameter is passed directly to a system command without sanitization, enabling an attacker to execute arbitrary operating-system commands on the device.
The vulnerability is reachable over the network without authentication or user interaction, corresponding to the CVSS 9.8 rating. An unauthenticated remote attacker can therefore obtain full control of the router, including the ability to read or modify configuration, exfiltrate traffic, or pivot into the attached network.
Public references consist solely of a proof-of-concept disclosure on GitHub; no vendor advisory or firmware patch is referenced. The associated EPSS score has remained flat at 0.0566 since publication, indicating no material increase in observed exploitation interest.
