Title: 2Wire Routers 'H04_POST' Access Validation Vulnerability
Severity: CRITICAL
Description:
2Wire routers are network devices designed for home and small-office setups.
Multiple 2Wire routers are prone to an access-validation vulnerability because they fail to adequately authenticate users before performing certain actions.
This issue occurs when the devices handle 'xslt' requests for the 'H04_POST' page. The requests contain arbitrary 'PASSWORD' parameter data and a valid username passed to the 'PASSWORD_CONF' parameter.
Unauthenticated attackers can leverage this issue to change the password of arbitrary user accounts on the router. Successful attacks will completely compromise affected devices.
2Wire routers that have the 'H04_POST' page are affected by this issue.
UPDATE: This BID has been retired because it has been found to be a duplicate of BID 27246 (2Wire Routers Cross-Site Request Forgery Vulnerability).
UPDATE (February 1, 2008): This BID is being reinstated. Further investigation and new information reveal that this vulnerability differs from the one described in BID 27246.
