Description

Use of Hard-coded Cryptographic Key vulnerability in Apache OpenMeetings. The remember-me cookie encryption key is set to default value in openmeetings.properties and not being auto-rotated. In case OM admin hasn't changed the default encryption key, an attacker who has stolen a cookie from a logged-in user can get full user credentials. This issue affects Apache OpenMeetings: from 6.1.0 before 9.0.0. Users are recommended to upgrade to version 9.0.0, which fixes the issue.
