Title: 2Wire Routers 'password_required.html' Password Reset Security Bypass Vulnerability
Severity: CRITICAL
Description:
2Wire routers are network devices designed for home and small-office setups.
Multiple 2Wire routers are prone to an security-bypass vulnerability because they fail to adequately authenticate users before performing certain actions. Specifically, unauthenticated attackers can change administrative passwords via the 'setup/password_required.html' script.
Successful attacks will completely compromise affected devices.
This issue may be related to the vulnerability described in BID 36031 (2Wire Routers 'CD35_SETUP_01' Access Validation Vulnerability).
We don't know which models and firmware versions are affected. We will update this BID when more details become available.
