vCenter Server 5.0/5.1 Update - CVE-2014-6593 (SKIP-TLS)

vcenter-server-logoVMware has published an update for vCenter Server 5.0 and 5.1 where CVE-2014-6593 (SKIP-TLS) has been fixed.

It was discovered that the SSL/TLS implementation in the JSSE component in OpenJDK failed to properly check whether the ChangeCipherSpec was received during the SSL/TLS connection handshake. A man-in-the-middle attacker could possibly use this flaw to force a connection to be established without encryption being enabled. The update has been already fixed in newer versions of vCenter Server (6.0a, 5.5 Update 2e). More information are available in VMSA-2015-0003.

Upgrade vCenter 5.1 to 5.5 error: "The existing ssl certificate is invalid"

The upgrade from vCenter Server 5.1 to vCenter Server 5.5 (5.5.0 and 5.5.0a) fails during the SSO installation with the following error message:

The existing ssl certificate is invalid

After verifying the certificate i could confirm that it is valid and not expired. After troubleshooting the update log I figured out that the problem was caused by a wrong registry entry. The old 5.1 installation was using an IP address instead of the vCenters FQDN.

  • See the vSphere Data Protection button in the vSphere Web Client
