TITLE

Xavi X7968 Vulnerable to cross-site request forgery

DESCRIPTION

Cross-site request forgery (CSRF) vulnerability in webconfig/admin_passwd/passwd.html/admin_passwd in Xavi X7968 allows remote attackers to hijack the authentication of administrators for requests that change the administrator password via the sysUserName, sysPassword, and sysCfmPwd parameters. The Xavi 7968 ADSL Router is an ADSL router device. There is a vulnerability in the Xavi 7968 ADSL Router. Because the program fails to properly validate user-submitted requests, an attacker can build a malicious URI, trick the user into parsing, and run privileged commands on the device, such as changing the configuration, performing a denial of service attack, or injecting arbitrary script code. Xavi 7968 ADSL Router is prone to cross-site scripting, HTML-injection and cross-site request forgery vulnerabilities. The attacker can exploit the issues to execute arbitrary script code in the context of the vulnerable site, potentially allowing the attacker to steal cookie-based authentication credentials, or perform certain administrative functions on victim's behalf. Other attacks are also possible. ---------------------------------------------------------------------- Become a PSI 3.0 beta tester!

This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected device. 2) The device's web interface allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. change an administrator's password or conduct script insertion attacks by tricking a logged in administrator into visiting a malicious web site. SOLUTION: Filter malicious characters and character sequences using a proxy. Do not browse untrusted sites or follow untrusted links while being logged-in to the device.
