An authentication bypass vulnerability was found in overt-engine. This flaw allows the creation of users in the system without authentication due to a flaw in the CreateUserSession command.

An HTML injection/reflected Cross-site scripting (XSS) vulnerability was found in the ovirt-engine. A parameter "errordescription" fails to sanitize the entry, allowing the vulnerability to trigger on the Windows Service Accounts home pages.

ovirt-engine 3.2 running on Linux kernel 3.1 and newer creates certain files world-writeable due to an upstream kernel change which impacted how python's os.chmod() works when passed a mode of '-1'.

The web console login form in ovirt-engine before version 4.2.3 returned different errors for non-existent users and invalid passwords, allowing an attacker to discover the names of valid user accounts.

A cross-site scripting vulnerability was reported in ovirt-engine's OAuth authorization endpoint. URL parameters would be included in the HTML response without escaping, allowing an attacker to craft malicious HTML pages that could run scripts in the context of the user's ovirt session.

A flaw was found in ovirt-engine 4.4.3 and earlier allowing an authenticated user to read other users' personal information, including name, email and public SSH key.

A flaw was found in Ovirt Engine's web interface in ovirt 4.4 and earlier, where it did not filter user-controllable parameters completely, resulting in a reflected cross-site scripting attack. This flaw allows an attacker to leverage a phishing attack, steal an unsuspecting user's cookies or other confidential information, or impersonate them within the application's context.

Ovirt-engine did not verify key attributes from the the vdsm X.509 certificates. This could allow a man-in-the-middle attacker to spoof an SSL certificate with invalid attributes that would otherwise prevent an certificate from being presented as valid

Ovirt Engine's web interface in ovirt 4.4.2 and earlier does not filter user controllable parameters completely, which may result in a reflected cross site scripting attack.
