An anonymous reader writes "2Wire manufactures DSL modems and routers for AT&T and other major carriers. Their devices suffer from a DNS redirection vulnerability that can be used as part of a variety of attacks, including phishing, identity theft, and denial of service. This exploit was publicly reported more than eight months ago and applies to nearly all 2Wire firmware revisions. The exploit itself is trivial to implement, requiring the attacker only to embed a specially crafted URL into a Web site or email. User interaction is not required, as the URL may be embedded as an image that loads automatically with the requested content. The 2Wire exploit bypasses any password set on the modem/router and is being actively exploited in the wild. AT&T has been deploying 2Wire DSL modems and router/gateways for years, so there exists a large vulnerable installed base. So far, AT&T/2Wire haven't done anything about this exploit." Update: 04/09 17:48 GMT by KD : AT&T spokesman Seth Bloom sends word that AT&T has not been ignoring the problem. According to Bloom: "The majority of our customers did not have gateways affected by this vulnerability. For those that did, as soon as we became aware of the issue, we expeditiously implemented a permanent solution to close the vulnerability. In fact, we've already updated the majority of affected 2Wire gateways, and we're nearing completion of the process. We've received no reports of any significant threats targeting our customers."
