Research by Context Information Security has identified potentially significant flaws in the implementation of Cloud infrastructure services offered by some providers, which could be putting their clients' data at risk. By exploiting the vulnerability, which revolves around data separation, Context consultants were able to gain access to some data left on other service users' 'dirty disks' (1), including fragments of customer databases and elements of system information that could, in combination with other data, allow an attacker to take control of other hosted servers.
