VAR-190001-0048
Vulnerability from variot - Updated: 2022-05-17 22:37Because 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? Fast vulnerability intelligence, threat handling, and setup in one tool.

DESCRIPTION: Two vulnerabilities have been reported in the ZTE ZXDSL 831 II modem, which can be exploited by malicious people to conduct cross-site request forgery attacks and to disclose sensitive information. This can be exploited to e.g. change an administrator's password by tricking a logged in administrator into visiting a malicious web site.
The vulnerabilities are reported in version 7.5.0a_Z29_OV. Other versions may also be affected.
SOLUTION: Restrict access to trusted users only. Do not browse untrusted websites or follow untrusted links while logged in to the application.
PROVIDED AND/OR DISCOVERED BY: Mehdi Boukazoula and Ibrahim Debeche.
