Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
