Apache OpenMeetings missing authentication and can allow user impersonation

Critical severity GitHub Reviewed Published Mar 28, 2023 to the GitHub Advisory Database • Updated Apr 4, 2023

Package

maven org.apache.openmeetings:openmeetings-parent (Maven)

Affected versions

>= 2.0.0, < 7.0.0

Patched versions

7.0.0

Description

The Apache Software Foundation's OpenMeetings from 2.0.0 before 7.0.0 is missing authentication on meeting invitation URLs. An invitation URL contains a hash that automatically logs in as the invited user. An unauthorized user could obtain this URL and log in to the meeting as an invited user, in effect elevating their privileges in the meeting room. OpenMeetings 7.0.0 disables this option if a contact is not selected.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
