Sensitive passwords used in deployment and configuration of oVirt Metrics, all versions. were found to be insufficiently protected. Passwords could be disclosed in log files (if playbooks are run with -v) or in playbooks stored on Metrics or Bastion hosts.

It was discovered that in the ovirt's REST API before version 4.3.2.1, RemoveDiskCommand is triggered as an internal command, meaning the permission validation that should be performed against the calling user is skipped. A user with low privileges (eg Basic Operations) could exploit this flaw to delete disks attached to guests.

ovirt-engine before version 4.1.7.6 with log level set to DEBUG includes passwords in the log file without masking. Only administrators can change the log level and only administrators can access the logs. This presents a risk when debug-level logs are shared with vendors or other parties to troubleshoot issues.

ovirt-engine before version ovirt 4.2.2 is vulnerable to an information exposure through log files. When engine-backup was run with one of the options "--provision*db", the database username and password were logged in cleartext. Sharing the provisioning log might inadvertently leak database passwords.

ovirt-engine up to version 4.2.3 is vulnerable to an unfiltered password when choosing manual db provisioning. When engine-setup was run and one chooses to provision the database manually or connect to a remote database, the password input was logged in cleartext during the verification step. Sharing the provisioning log might inadvertently leak database passwords.

ovirt-engine API and administration web portal before versions 4.2.2.5, 4.1.11.2 is vulnerable to an exposure of Power Management credentials, including cleartext passwords to Host Administrators. A Host Administrator could use this flaw to gain access to the power management systems of hosts they control.

oVirt Engine before 4.0.3 does not include DWH_DB_PASSWORD in the list of keys to hide in log files, which allows local users to obtain sensitive password information by reading engine log files.

oVirt Engine before 3.5.0 does not include the HTTPOnly flag in a Set-Cookie header for the session IDs, which makes it easier for remote attackers to obtain potentially sensitive information via script access to this cookie.

The REST API in oVirt 3.4.0 and earlier stores session IDs in HTML5 local storage, which allows remote attackers to obtain sensitive information via a crafted web page.

Session fixation vulnerability in the web admin interface in oVirt 3.4.0 and earlier allows remote attackers to hijack web sessions via unspecified vectors.
