QFinch assessment
Improper input handling in a modem-management administrative CLI command on TP-Link Archer NX200, NX210, NX500 and NX600 allows crafted input to be executed as part of an operating system command. An authenticated attacker with administrative privileges may execute arbitrary commands on the operating system, impacting the confidentiality, integrity, and availability of the device.
