Atlassian Confluence CVE-2022-26138 Weak Authentication Vulnerability

Description

When the Questions for Confluence app is enabled on Confluence Server or Data Center, it creates a Confluence user account with the username disabledsystemuser. This account is intended to aid administrators that are migrating data from the app to Confluence Cloud. The disabledsystemuser account is created with a hardcoded password and is added to the confluence-users group, which allows viewing and editing all non-restricted pages within Confluence by default. A remote, unauthenticated attacker with knowledge of the hardcoded password could exploit this to log into Confluence.
