Multiple D-Link Routers Vulnerability

Multiple D-Link routers suffer from insecure implementations of the Home Network Administration Protocol which allow unauthenticated and/or unprivileged users to view and configure administrative settings on the router. Further, the mere existence of HNAP allows attackers to completely bypass the CAPTCHA login features that D-Link has made available in recent firmware releases. It is suspected that most, if not all, D-Link routers manufactured since 2006 have HNAP support and are vulnerable to one of the below described vulnerabilities. However, only the following routers and firmware versions have been confirmed to date: DI-524 hardware version C1, firmware version 3.23; DIR-628 hardware version B2, firmware versions 1.20NA and 1.22NA; DIR-655 hardware version A1, firmware version 1.30EA.

Mitigation:

Users should update their routers to the latest firmware version available from the vendor.
