The Huawei D100 allows remote attackers to obtain sensitive information via a direct request to (1) lan_status_adv.asp, (2) wlan_basic_cfg.asp, or (3) lancfg.asp in en/, related to use of JavaScript to protect against reading file contents.

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.

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 Huawei D100 has (1) a certain default administrator password for the web interface, and does not force a password change; and has (2) a default password of admin for the admin account in the telnet interface; which makes it easier for remote attackers to obtain access.
