The Authentication, Authorization and Accounting (AAA) module in the USG products has a buffer overflow vulnerability. A remote attacker can send crafted Enterprise Application Platform (EAP) packets to the USG products through a Remote Authentication Dial In User Service (RADIUS) server which has completed authentication with the USG products. Successful exploit could allow the attacker to execute arbitrary code on the USG products. (Vulnerability ID: HWPSIRT-2016-06054)
This vulnerability has been assigned Common Vulnerabilities and Exposures (CVE) ID: CVE-2016-6669.
Huawei has released software updates to fix the vulnerability. This advisory is available at the following link:

Successful exploit could allow the attacker to execute arbitrary code on the USG products.
The vulnerability classification has been performed by using the CVSSv2 scoring system (http://www.first.org/cvss/).
Base Score: 7.1 (AV:N/AC:H/Au:S/C:C/I:C/A:C)
Temporal Score: 5.9 (E:F/RL:O/RC:C)
1. Prerequisite:
The attacker can control a RADIUS server which has completed authentication with the USG products.
2. Attacking procedure:
Due to insufficient validation on a specific field in EAP packets, a remote attacker can send crafted EAP packets to the USG products through a RADIUS server which has completed authentication with the USG products. Successful exploit could allow the attacker to execute arbitrary code on the USG products.
