The Huawei D100 stores the administrator's account name and password in cleartext in a cookie, which allows context-dependent attackers to obtain sensitive information by (1) reading a cookie file, by (2) sniffing the network for HTTP headers, and possibly by using unspecified other vectors.

The default configuration of the Wi-Fi component on the Huawei D100 does not use encryption, which makes it easier for remote attackers to obtain sensitive information by sniffing the network.
