TITLE

ZTE ZXDSL 831-II Modem Information Disclosure Vulnerability

DESCRIPTION

Because the application displays the authentication credentials in the accessaccount.cgi script, an attacker can gain sensitive information. ZTE ZXDSL 831-II is an ADSL device issued by ZTE Corporation. A cross-site request forgery vulnerability exists in the ZTE ZXDSL 831 II modem. Since the application WEB interface allows certain operations to be performed through HTTP requests, without strict verification of the request, the attacker constructs a malicious link, entices the user to resolve, and can perform various operations with administrator privileges. Such as changing the administrator password and so on. ZTE ZXDSL 831-II is prone to a cross-site request-forgery vulnerability and an information-disclosure vulnerability. Attackers can exploit the information-disclosure issue to obtain sensitive information that may aid in launching further attacks. Exploiting the cross-site request-forgery may allow a remote attacker to perform certain administrative actions and gain unauthorized access to the affected application. Other attacks are also possible. ---------------------------------------------------------------------- Ovum says ad hoc tools are out-dated. The best practice approach?
