Original release date: November 24, 2015 | Last revised: November 25, 2015

Dell consumer personal computers using the preinstalled certificate authority (CA) root certificate (eDellRoot) contain a critical vulnerability. Exploitation of the vulnerability could allow a remote attacker to read all encrypted web browser traffic (HTTPS), successfully impersonate (spoof) any website, or perform other attacks on the affected system.

The eDellRoot certificate originated from an update to the Dell Foundation Services (DFS) application on August 18, 2015.  As of November 23, that update is no longer being provided. The certificate was also preinstalled on some systems between November 20-23, 2015. Dell is pushing a DFS software update to remove the vulnerable certificate from affected systems.

US-CERT encourages users and administrators to review Vulnerability Note VU#870761 and Dell’s blog post for more information and guidance on removing the certificate.
