Description

An OS command injection vulnerability exists in the TR-069 / CWMP management interface of Archer VX1800v v1 due to insufficient input validation and sanitization of parameters, allowing crafted input to be executed as system-level commands. Exploitation requires specific conditions such as TR-069 being enabled and ability to influence ACS-delivered commands, compromise or control an ACS server. Successful exploitation may allow arbitrary command execution with root privileges, resulting in complete compromise of the device.
