Multiple D-Link Routers Authentication Bypass Vulnerability

www.hx99.net    时间: 2010-01-14    阅读: 次     整理: 华西安全网

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: 

  

         1) DI­524 hardware version C1, firmware version 3.23 

         2) DIR­628 hardware version B2, firmware versions 1.20NA and 1.22NA 

         3) DIR­655 hardware version A1, firmware version 1.30EA
