Session fixation vulnerability in the vSphere Web Client Server in VMware vCenter Server 5.0 before Update 3 allows remote attackers to hijack web sessions and gain privileges via unspecified vectors.

The management interface in the Central Software component in Cisco Unified Computing System (UCS) does not properly validate the identity of vCenter consoles, which allows man-in-the-middle attackers to read or modify an inter-device data stream by spoofing an identity, aka Bug ID CSCtk00683.

VMware vCenter Chargeback Manager (aka CBM) before 2.5.1 does not proper handle uploads, which allows remote attackers to execute arbitrary code via unspecified vectors.

The SSL functionality in Cisco NX-OS on the Nexus 1000V does not properly verify X.509 certificates, which allows man-in-the-middle attackers to spoof servers, and intercept or modify Virtual Supervisor Module (VSM) to VMware vCenter communication, via a crafted certificate, aka Bug ID CSCud14837.

VMware vCenter Server Appliance (vCSA) 5.1 before Update 1 allows remote authenticated users to create or overwrite arbitrary files, and consequently execute arbitrary code or cause a denial of service, by leveraging Virtual Appliance Management Interface (VAMI) web-interface access.

VMware vCenter Server 5.1 before Update 1, when anonymous LDAP binding for Active Directory is enabled, allows remote attackers to bypass authentication by providing a valid username in conjunction with an empty password.

VMware vCenter Server Appliance (vCSA) 5.1 before Update 1 allows remote authenticated users to execute arbitrary programs with root privileges by leveraging Virtual Appliance Management Interface (VAMI) access.

VMware vCenter Server 4.0 before Update 4b, 5.0 before Update 2, and 5.1 before 5.1.0b; VMware ESXi 3.5 through 5.1; and VMware ESX 3.5 through 4.1 do not properly implement the Network File Copy (NFC) protocol, which allows man-in-the-middle attackers to execute arbitrary code or cause a denial of service (memory corruption) by modifying the client-server data stream.

VMware vCenter Server 4.1 before Update 3 and 5.0 before Update 2, and vCSA 5.0 before Update 2, allows remote attackers to cause a denial of service (disk consumption) via vectors that trigger large log entries.

VMware vCenter Server 4.0 before Update 4b and 4.1 before Update 3a, VMware VirtualCenter 2.5, VMware vSphere Client 4.0 before Update 4b and 4.1 before Update 3a, VMware VI-Client 2.5, VMware ESXi 3.5 through 4.1, and VMware ESX 3.5 through 4.1 do not properly implement the management authentication protocol, which allow remote servers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors.
