Security Advisory

1) Command injection


The vulnerability allows a remote attacker with administrator privileges to perform command injection attack on the target system.

The weakness exists due to the implementation of the TR-064 (technical report standard), an application layer protocol for remote management, in the Huawei devices was exposed on the public Internet through Universal Plug and Play (UPnP) protocol at port 37215. A remote attacker can inject shell meta-characters “$()” in the NewStatusURL and NewDownloadURL, inject arbitrary commands and execute arbitrary code.

Successful exploitation of the vulnerability allows to download and execute the malicious payload on the Huawei routers and upload Satori botnet that may result in system compromise.

Note: the vulnerability is being actively exploited.


Customers can take the following measures to circumvent or prevent the exploit of this vulnerability. For details, consult the local service provider or Huawei TAC.

(1)     Configure the built-in firewall function.

(2)     Change the default password.

(3)     Deploy a firewall at the carrier side.

The customers can deploy Huawei NGFWs (Next Generation Firewall) or data center firewalls, and upgrade the IPS signature database to the latest version IPS_H20011000_2017120100 released on December 1, 2017 to detect and defend against this vulnerability exploits initiated from the Internet.
