info:
  name: Atlassian Questions For Confluence - Hardcoded Credentials
  author: HTTPVoid
  severity: critical
  description: |
    Atlassian Questions For Confluence contains a hardcoded credentials vulnerability. When installing versions 2.7.34, 2.7.35, and 3.0.2, a Confluence user account is created in the confluence-users group with the username disabledsystemuser and a hardcoded password. A remote, unauthenticated attacker with knowledge of the hardcoded password can exploit this vulnerability to log into Confluence and access all content accessible to users in the confluence-users group.
  remediation: |
    Update the Atlassian Questions For Confluence plugin to the latest version, which removes the hardcoded credentials.
