VMware ESX contains an insufficient logging vulnerability. A malicious administrator could exploit this issue to perform certain operations without them being logged.

VMware Workstation 9.x before 9.0.1, VMware Player 5.x before 5.0.1, VMware Fusion 5.x before 5.0.1, VMware ESXi 4.0 through 5.1, and VMware ESX 4.0 and 4.1 allow guest OS users to cause a denial of service (VMX process disruption) by using an invalid port.

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.

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.
