critical Nessus Plugin ID 185949

Language:

Synopsis

A virtualization appliance installed on the remote host is affected by a remote code execution vulnerability.

Description

VMware Cloud Director Appliance contains an authentication bypass vulnerability in case VMware Cloud Director Appliance was upgraded to 10.5 from an older version. On an upgraded version of VMware Cloud Director Appliance 10.5, a malicious actor with network access to the appliance can bypass login restrictions when authenticating on port 22 (ssh) or port 5480 (appliance management console) . This bypass is not present on port 443 (VCD provider and tenant login). On a new installation of VMware Cloud Director Appliance 10.5, the bypass is not present.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
