VMware ESX 2.0.x < 2.0.2 and 2.x < 2.5.2 patch 4 - Privilege Escalation via Base64-Encoded Cookie Credentials
VMware ESX Server 2.0.x before 2.0.2 and 2.x before 2.5.2 patch 4 stores authentication credentials in base 64 encoded format in the vmware.mui.kid and vmware.mui.sid cookies, which allows attackers to gain privileges by obtaining the cookies using attacks such as cross-site scripting (CVE-2005-3619).
