What the flaw is
Atlassian Questions For Confluence App has hard-coded credentials, exposing the username and password in plaintext. A remote unauthenticated attacker can use these credentials to log into Confluence and access all content accessible to users in the confluence-users group.
CISA's description
The Atlassian Questions For Confluence app for Confluence Server and Data Center creates a Confluence user account in the confluence-users group with the username disabledsystemuser and a hardcoded password. A remote, unauthenticated attacker with knowledge of the hardcoded password could exploit this to log into Confluence and access all content accessible to users in the confluence-users group. This user account is created when installing versions 2.7.34, 2.7.35, and 3.0.2 of the app.
