What is CVE-2015-7257?

ZTE ADSL ZXV10 W300 modems exhibit an authorization bypass vulnerability that allows remote authenticated non-administrator users to manipulate the admin password. By intercepting the outgoing password change request, an attacker can alter the username parameter from 'support' to 'admin', thereby gaining unauthorized access. This flaw emphasizes the need for secure handling of privileged access requests and effective user authentication methods to prevent unauthorized modifications.
