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).

vmware-config.pl in VMware for Linux, ESX Server 2.x, and Infrastructure 3 does not check the return code from a Perl chmod function call, which might cause an SSL key file to be created with an unsafe umask that allows local users to read or modify the SSL key.

Cross-site request forgery (CSRF) vulnerability in the management interface for VMware ESX Server 2.0.x before 2.0.2 patch 1, 2.1.x before 2.1.3 patch 1, and 2.x before 2.5.3 patch 2 allows allows remote attackers to perform unauthorized actions as the administrator via URLs, as demonstrated using the setUsr operation to change a password. NOTE: this issue can be leveraged with CVE-2005-3619 to automatically perform the attacks.

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.

The management interface for VMware ESX Server 2.0.x before 2.0.2 patch 1, 2.1.x before 2.1.3 patch 1, and 2.x before 2.5.3 patch 2 records passwords in cleartext in URLs that are stored in world-readable web server log files, which allows local users to gain privileges.

The configuration of VMware ESX Server 2.x, 2.0.x, 2.1.x, and 2.5.x allows local users to cause a denial of service (shutdown) via the (1) halt, (2) poweroff, and (3) reboot scripts executed at the service console.

Unspecified vulnerability in the Management Interface in VMware ESX Server 2.x up to 2.5.x before 24 December 2005 allows "remote code execution in the Web browser" via unspecified attack vectors, probably related to cross-site scripting (XSS).
