VMware vCenter Server: Man-in-the-Middle of Client Integration Plugin

Synthesis of the vulnerability

An attacker can act as a Man-in-the-Middle of Client Integration Plugin on VMware vCenter Server, in order to read or write data in the session.
Impacted products: vCenter Server, VMware vSphere, VMware vSphere Hypervisor.
Severity: 2/4.
Consequences: data reading, data creation/edition.
Provenance: intranet server.
Creation date: 15/04/2016.
Identifiers: CERTFR-2016-AVI-130, CVE-2016-2076, VIGILANCE-VUL-19388, VMSA-2016-0004.

Description of the vulnerability

The VMware vCenter Server product uses the TLS protocol, in order to create secure sessions with the Client Integration Plugin.

However, the X.509 certificate and the service identity are not correctly checked.

An attacker can therefore act as a Man-in-the-Middle of Client Integration Plugin on VMware vCenter Server, in order to read or write data in the session.

vulnerability bulletin 19383

Zend Framework: low entropy

Synthesis of the vulnerability

An attacker can potentially predict randoms used by Zend Framework, in order to bypass security features.
Impacted products: Zend Framework.
Severity: 1/4.
Consequences: data reading, data creation/edition.
Provenance: user account.
Creation date: 14/04/2016.
Identifiers: VIGILANCE-VUL-19383, ZF2016-01.

Description of the vulnerability

The Zend Framework product uses a random generator in the following methods:
 - Zend_Ldap_Attribute::createPassword
 - Zend_Form_Element_Hash::_generateHash
 - Zend_Gdata_HttpClient::filterHttpRequest
 - Zend_Filter_Encrypt_Mcrypt::_srand
 - Zend_OpenId::randomBytes

However, these methods use rand() or mt_rand(), which are not cryptographically secure.

An attacker can therefore potentially predict randoms used by Zend Framework, in order to bypass security features.
