Ovirt-engine: potential exposure of cleartext provider passwords via web ui

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.

Ovirt: authentication bypass

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.

kernel: improper initialization of the "flags" member of the new pipe_buffer

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.

ovirt-engine: HTML Injection/ Reflected XSS on Windows Service Accounts homepages

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.

ovirt-engine-webadmin: does not invalidate all sessions upon logout

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-engine: DWH_DB_PASSWORD is in cleartext in the log files

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-node: unsafe quoting in command lines

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-api: session ID stored in HTML5 local storage

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.

ovirt-engine-webadmin: HttpOnly flag is not included when the session ID is set

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.

ovirt-engine-webadmin: session fixation

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 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.

sanlock world writable /var/log/sanlock.log

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.

ovirt-log-collector: RHVM admin password is logged unfiltered

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

kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS

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.

vdsm: disclosure of sensitive values in log files

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.

ovirt-engine: non-admin user is able to access other users public SSH key

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.

ovirt-engine: Reflected cross site scripting vulnerability

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: Missing permissions check in web ui allows a user with basic privileges to delete disks

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.

vdsm: privilege escalation to root via systemd_run

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.

ovirt-engine: response_type parameter allows reflected XSS

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.
