Recently shipped Dell systems have been found to include a special Root CA Certificate and private key, "eDellRoot". All systems apparently use the same key and certificate. Using the "secret" key, anybody could create certificates for any domain, and Dell systems with this eDellRoot certificate would trust it. The key is part of "Dell Foundation Services". To test if your system is affected, see: https://edell.tlsfun.de To remove the certificate if you are affected: - stop and disable Dell Foundation Services For details about managing Root CAs see https://technet.microsoft.com/en-us/library/cc754841.aspx In this case, it is not sufficient to just remove the CA. Dell Foundation Services will reinstall it. This is why you need to disable Dell Foundation Services first, or delete the Dell.Foundation.Agent.Plugins.eDell.dll. --- |

Do you have any more details about how the site testing for this works? I'm getting a positive test for a system that has been wiped and imaged.

I tried the test on Firefox, Chrome and IE 11. All 3 return that I don't have the certificate. The only exception is IE 11 asked if I wished to enable the blocked content of the website. When I click yes, I then receive message that I have the vulnerable edell certificate. It's not in the trusted certificate store in my system. I'm running an HP tower.

Hi,
Superfish 2.0 is not finished yet - reading the German (sorry, didn't find/search for a translation) article [1]. After Downloading and Installing "Dell System Detect" you are proud owner of another root certificate with corresponding privte key [1] http://www.golem.de/news/https-verschluesselung-noch-ein-gefaehrliches-dell-zertifikat-1511-117615.html |
