Apache CloudStack 4.0.0 before 4.0.2 and Citrix CloudPlatform (formerly Citrix CloudStack) 3.0.x before 3.0.6 Patch C uses a hash of a predictable sequence, which makes it easier for remote attackers to guess the console access URL via a brute force attack.

Citrix CloudPlatform (formerly Citrix CloudStack) 3.0.x before 3.0.6 Patch C does not properly restrict access to VNC ports on the management network, which allows remote attackers to have unspecified impact via unknown vectors.

Apache CloudStack 4.0.0 before 4.0.2 and Citrix CloudPlatform (formerly Citrix CloudStack) 3.0.x before 3.0.6 Patch C allows remote attackers to bypass the console proxy authentication by leveraging knowledge of the source code.

Apache CloudStack 4.0.0-incubating and Citrix CloudPlatform (formerly Citrix CloudStack) before 3.0.6 stores sensitive information in the log4j.conf log file, which allows local users to obtain (1) the SSH private key as recorded by the createSSHKeyPair API, (2) the password of an added host as recorded by the AddHost API, or the password of an added VM as recorded by the (3) DeployVM or (4) ResetPasswordForVM API.
