The remote Dell Integrated Remote Access Controller 6 (iDRAC6) is affected by the following vulnerabilities :
A flaw exists in the testurls.html page that allows a remote attacker to authenticate as root. A remote attacker can exploit this to enable root user access over SSH, telnet, and other services. (CVE-2013-4785)
A flaw exists in the Intelligent Platform Management Interface (IPMI) implementation due to improper handling of connections. An unauthenticated, remote attacker can exploit this to exhaust system resources, resulting in a denial of service condition.
