OS Command Injection in Archer VX1800v (CVE-2026-15427)
Summary
OS command injection in Archer VX1800v (CVE-2026-15427). Successful exploitation can lead to full system takeover.
Original description
The description as published by the source.
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.
