Cross-site scripting (XSS) vulnerability in the management interface for VMware ESX 2.5.x before 2.5.2 upgrade patch 2, 2.1.x before 2.1.2 upgrade patch 6, and 2.0.x before 2.0.1 upgrade patch 6 allows remote attackers to inject arbitrary web script or HTML via messages that are not sanitized when viewing syslog log files.
VMware ESX server versions prior to 2.5.2 upgrade patch 2, prior to 2.1.2 upgrade patch 6, and prior to 2.0.1 upgrade patch 6 suffer from a cross site scripting issue.
