Security Advisory - Several Vulnerabilities in Huawei Honor Routers

  • SA No:huawei-sa-20160607-01-honorrouter
  • Initial Release Date: 2016-06-07
  • Last Release Date: 2016-06-22

Huawei Honor routers do not verify some parameters. As a result, sensitive information may be displayed, causing the leak of sensitive information. (Vulnerability ID: HWPSIRT-2016-05053)
This vulnerability has been assigned Common Vulnerabilities and Exposures (CVE) ID: CVE-2016-5367.

Huawei Honor routers do not restrict some interfaces. As a result, a file injection vulnerability occurs, allowing attackers to tamper with configuration data. (Vulnerability ID: HWPSIRT-2016-05052)
This vulnerability has been assigned Common Vulnerabilities and Exposures (CVE) ID: CVE-2016-5366.

Huawei Honor routers do not verify some parameters. When an attacker injects malicious information, a stack overflow may occur. As a result, the attacker can obtain the root privilege and run shell commands. (Vulnerability ID: HWPSIRT-2016-05051)

This vulnerability has been assigned Common Vulnerabilities and Exposures (CVE) ID: CVE-2016-5365.

 Huawei has released software updates to fix these vulnerabilities. This advisory is available at the following link:

An attacker can exploit the three vulnerabilities to obtain sensitive information, and then inject files and modify configuration information based on the sensitive information. When an Honor router parses the injected information, stack overflow may occur. As a result, the attacker can obtain the root privilege and run shell commands.

The vulnerability classification has been performed by using the CVSSv2 scoring system (http://www.first.org/cvss/).

HWPSIRT-2016-05053:

Base Score: 3.3 (AV:A/AC:L/Au:N/C:P/I:N/A:N)

Temporal Score: 2.7 (E:F/RL:O/RC:C)

HWPSIRT-2016-05052:

Base Score: 3.3 (AV:A/AC:L/Au:N/C:N/I:P/A:N)

Temporal Score: 2.7 (E:F/RL:O/RC:C)

 

HWPSIRT-2016-05051:

Base Score: 6.8 (AV:A/AC:H/Au:N/C:C/I:C/A:C)

Temporal Score: 5.6 (E:F/RL:O/RC:C)

HWPSIRT-2016-05053:

1. Prerequisite: 

The attacker has connected to the LAN through a LAN port or Wi-Fi network. 

2. Attacking procedure: 

After connecting to an Honor router through an open port, sensitive information may be displayed, causing the leak of sensitive information. 


HWPSIRT-2016-05052:

 1. Prerequisite: 

The attacker has connected to the LAN through a LAN port or Wi-Fi network. 

2. Attacking procedure: 

After connecting to an Honor router through an open port, trigger the file injection vulnerability based on the obtained sensitive information, and allowing attackers to tamper with configuration data.


HWPSIRT-2016-05051:

1. Prerequisite: 
The attacker has connected to the LAN through a LAN port or Wi-Fi network.

2. Attacking procedure: 

After connecting to an Honor router through an open port, the attacker can exploit the information leak vulnerability and file injection vulnerability. When the Honor router parses the injected file, the stack overflow vulnerability is triggered. As a result, the attacker can obtain the root privilege and run shell commands.
