Huawei home gateways WS318 with software V100R001C01B022 and earlier versions are affected by the PIN offline brute force cracking vulnerability of the WPS protocol because the random number generator (RNG) used in the supplier's solution is not random enough. As a result, brute force cracking the PIN code is easier. After an attacker cracks the PIN, the attacker can access the Internet via the cracked device.

There is a Cross-Site Scripting(XSS) vulnerability in HUAWEI WS318n product when processing network settings. Due to insufficient validation of user input, a local authenticated attacker could exploit this vulnerability by injecting special characters. Successful exploit could cause certain information disclosure. Affected product versions include: WS318n-21 10.0.2.2, 10.0.2.5 and 10.0.2.6.
