Several security issues have been identified within Citrix XenServer. These issues could, if exploited, allow an authenticated administrator to perform a denial-of-service attack against the host, even when that administrator has a less-privileged RBAC role (e.g. read-only). In addition, the issues could permit an attacker with the ability to influence NTP traffic on the management network to disrupt time synchronization on the host until the next reboot. The following vulnerabilities have been addressed: CVE-2017-5572 (Low): Authenticated read-only administrator can corrupt host database CVE-2017-5573 (Low): Authenticated read-only administrator can cancel tasks of other administrators CVE-2015-5300, CVE-2015-7704, CVE-2015-7705 (Low): NTP updates. Customers who have not enabled NTP are unaffected by the NTP issues. Customers who have not enabled RBAC are unaffected by the RBAC issues. Customers using Citrix XenServer 6.0.2 in the Common Criteria configuration are unaffected by the RBAC issues.

Affected Versions:
XenServer 7.0 XenServer 6.5 XenServer 6.2.0 XenServer 6.0.2

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
