OvirtCVEs & Vulnerabilities

A flaw was found in oVirt. A user with administrator privileges, including users with the ReadOnlyAdmin permission, may be able to use browser developer tools to view Provider passwords in cleartext.

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 "error_description" fails to sanitize the entry, allowing the vulnerability to trigger on the Windows Service Accounts home pages.

It was found that the ovirt-log-collector/sosreport collects the RHV admin password unfiltered. Fixed in: sos-4.2-20.el8_6, ovirt-log-collector-4.4.7-2.el8ev

A race condition was found in vdsm. Functionality to obfuscate sensitive values in log files that may lead to values being stored in clear text.

A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.

A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network.

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.

A cross-site scripting vulnerability was reported in the oVirt-engine's OAuth authorization endpoint before version 4.3.8. URL parameters were included in the HTML response without escaping. This flaw would allow an attacker to craft malicious HTML pages that can run scripts in the context of the user's oVirt session.

oVirt Node: Lock screen accepts F2 to drop to shell causing privilege escalation

mom creates world-writable pid files in /var/run

vdsm: certificate generation upon node creation allowing vdsm to start and serve requests from anyone who has a matching key (and certificate)

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'.

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.

During HE deployment via cockpit-ovirt, cockpit-ovirt generates an ansible variable file `/var/lib/ovirt-hosted-engine-setup/cockpit/ansibleVarFileXXXXXX.var` which contains the admin and the appliance passwords as plain-text. At the of the deployment procedure, these files are deleted.

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.

A vulnerability was discovered in vdsm, version 4.19 through 4.30.3 and 4.30.5 through 4.30.8. The systemd_run function exposed to the vdsm system user could be abused to execute arbitrary commands as root.

It was found that vdsm before version 4.20.37 invokes qemu-img on untrusted inputs without limiting resources. By uploading a specially crafted image, an attacker could cause the qemu-img process to consume unbounded amounts of memory of CPU time, causing a denial of service condition that could potentially impact other users of the host.

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-ansible-roles before version 1.0.6 has a vulnerability due to a missing no_log directive, resulting in the 'Add oVirt Provider to ManageIQ/CloudForms' playbook inadvertently disclosing admin passwords in the provisioning log. In an environment where logs are shared with other parties, this could lead to privilege escalation.

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.

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.

An information disclosure in ovirt-hosted-engine-setup prior to 2.2.7 reveals the root user's password in the log file.

oVirt 3.2.2 through 3.5.0 does not invalidate the restapi session after logout from the webadmin, which allows remote authenticated users with knowledge of another user's session data to gain that user's privileges by replacing their session token with that of another user.

ovirt_safe_delete_config in ovirtfunctions.py and other unspecified locations in ovirt-node 3.0.0-474-gb852fd7 as packaged in Red Hat Enterprise Virtualization 3 do not properly quote input strings, which allows remote authenticated users and physically proximate attackers to execute arbitrary commands via a ; (semicolon) in an input string.

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.

The setup_logging function in log.h in SANLock uses world-writable permissions for /var/log/sanlock.log, which allows local users to overwrite the file content or bypass intended disk-quota restrictions via standard filesystem write operations.

The python SDK before 3.1.0.6 and CLI before 3.1.0.8 for oVirt 3.1 does not check the server SSL certificate against the client keys, which allows remote attackers to spoof a server via a man-in-the-middle (MITM) attack.
