Description

An OS command injection vulnerability exists in Archer VX800v v1 due to insufficient input sanitization of the domain name parameter. An adjacent attacker who can access the relevant HTTP interface can modify the parameter to inject shell metacharacters, resulting in arbitrary code execution with root privileges. Successful exploitation may allow remote code execution and complete compromise of the device.
